Calcium in crops: why proper assimilation is important

calcio en los cultivos

Calcium in crops plays a key role in agricultural development. Its existence guarantees firmer fruits. Agricultural calcium is necessary not only in structural strengthening of walls but also in the elasticity of the vegetal tissue. It is essential to have resistant and healthy plants.

Calcium shortage severely affects the quality of fruits and crop yield. This is the reason why an inappropriate assimilation can cause losses in the market value. Fortunately, there are treatments to improve calcium assimilation in crops. Its application is markedly necessary at the beginning of spring, when climatic conditions such as thermal amplitude between day and night can subject plants to stressful situations.

Calcium in crops is transported internally by xylem, but calcium has low mobility within the plant. Translocation results in a difficult process, since only a small percentage of calcium is translocated to the fruits from the surrounding leaves.

There are many climatic factors affecting calcium assimilation in crops. High temperatures on sunny days, wet and dry winds, and low relative humidity may become factors promoting high levels of transpiration. When this transpiration stream is too high towards the foliar organs, contribution of calcium to the fruit is restricted. In other words, for calcium is more difficult to reach those organs with low transpiration rate.

As we saw in an earlier entry, calcium deficiency in crops is observed in alterations such as BER (blossom end rot) in tomato and pepper. In strawberry or lettuce symptoms are perceived at the end of the expanding leaves (tip burn).

Guaranteeing contribution of calcium in crops

By evaluating calcium status in plants, it is possible to diagnose disorders like BER. In order to prevent such deficiencies, Seipasa has developed the Calcisei line of products. These products, formulated with calcium, play a pivotal role in crop development. Besides contributing to prevent deficiencies such as BER, tip burn or bitter pit in tomato and apple, the Calcisei line is specifically prepared for the structural strengthening of cell walls and membranes, as well as the management of soils with high content of salt.

Within this line, Calimax is a treatment designed to prevent calcium deficiencies in crops while confronting physiopathies. Calimax improves soil structure, promotes optimal root development and regulates imbalances due to lack of calcium.

Guadal Ca has been produced to avoid problems of internal decay and cracked fruits, as well as to confront apical rot, tip burn in horticultural crops. Lack of calcium usually concentrates on young leaves and fruits, since these are the organs having major transpiration difficulties. Guadal Ca is especially recommended for foliar applications in the second half of the crop cycle given the rapid absorption and total safety.

Apart from the contribution of calcium, the organic matter content of the Calcisei line brings significant benefits to the crop, especially in the post-harvest quality.

Soil correctors

Farmers are aware of how important is to have calcium in soils. Calcium deficiencies in plants can be observed in soils where there is an excess of nitrogen fertilizer, in substrates with alkaline pH, with episodes of water stress or with salt excess, among other factors. Within the Calcisei line, Miñosal is a corrector of saline and saline-sodic soils. It can be used both in soils having salinity problems and in areas where irrigation water quality makes it necessary.

Biostimulant Kynetic4

Biostimulant for flowering and fruit set: Kynetic4® acts in this way

Kynetic4® biostimulant represents a significant energy boost that gets better bloom, an optimal pollination and fertilization, and an excellent fruit set. It also acts as a protective barrier against possible plant stress conditions

Watch in this video the spectacular results of  the application of  this latest generation biostimulant

The action of the SEIPASA’s specialized biostimulant Kynetic4® on vegetable and fruit evidence a significant increase in the harvest. This cause and effect relationship has been demonstrated in research by agronomists. In the almond crops tested, productivity increases between 8% and 15%, reaching values even higher in vegetables. In fact, the application of Kynetic4® in zucchini reduces the use of hormone in about 60% with no significant differences between the different tested treatments.

These are just some of the results of the various tests carried out with this biostimulant, which have reported excellent results, a fact that farmers who have used it are already showing their crops.

But what is what brings Kynetic4® to get these quotas profitability? Based on the action of a studied combination of physiological intermediaries and vegetable amino acids, this biostimulant provides crops short chain substances rapidly assimilated by the plant, and peptides of long chain that improve adherence and effect of the product.

Flowering, fertilization  and flower set

Since its application involves an energy stimulation at times of peak demand, its employment is key in important stages such as flowering, fertilization and fruit set.

Kynetic4® manages to increase its vegetative growth and improve final output, not only in terms of quantitative parameters but also qualitative. Color, smoothness, size and taste are favored by the application of this biestimulant created thanks to recent advances in natural technology.

Effective pollination

With the application of a this formulated, the crop can achieve an effective pollination less determined by the natural factors that influence it, such as air temperatura (heat accelerates and cold retards the growth of the pollen tube, although it should be noted that high temperatures also accelerate the degeneration of stigma and decrease the longevity of the egg), rain (rain can wash the stigma and prevent the continuation of the process of fertilization), the amount of pollen captured or nutritional status of the plant.

In spite of the fact that the latter aspect requires appropriate management of fertilization since the beginning of cycle to avoid deficiencies during fertilization, the use of Kynetic4® manages to take advantage to the most of the nutrients in this stage.

Powerful action against crop stress

Also, Kynetic4® provides greater adaptability of the plant to stress conditions: drought, frost, transplants, extreme temperatures, diseases, pests…

This biostimulant keeps crops in excellent health vegetable to successfully face these situations and, once overcome the circumstances of stress, stimulates the recovery of the plant, since it promotes the restoration of plant tissues.

Furthermore, as an added value, it has high efficiency as a natural chelator, unblocking soils and facilitating absorption and assimilation of other compounds.

Promotes the effect of foliar fertilizers and herbicides

In this regard, polypeptides compounds in Kynetic4® formulation reduce surface tension and facilitate its use as a synergist in applying foliar fertilizers, facilitating their absorption, and herbicides, promoting their effect.

Specially selected amino acids in this biostimulant play its action on interest routes improving nutrient uptake and inducing protein and phytohormone synthesis .

This way, glutamic acid stimulates the growth of root, leaf and floral meristems, favors the opening of the stomata and plays an important role in plant nitrogen as a nature reserve.

Glycine, glutamic with, is essential in the formation of plant tissue and chlorophyll synthesis, and promotes the transport of micronutrients by the plant. Other amino acids as lysine and proline are essential in the flowering stage since, the first one increase pollen germination, and the second one improves fertility and regulates water balance.

But, in addition, Kynetic4® is enriched by organic matter and nitrogen. Nitrogen is vital to increase the longevity of the eggs.

Meanwhile, fulvic acids influence the health of the rhizosphere through its ability to multiply beneficial microorganisms, which are of great importance to keep out pathogens and pests.

Vines and olive trees: Soil preparation for a successful campaign

When the time comes to fertilize vines and olive trees, the question to be asked is which product to use to achieve the best results.

The correct soil preparation in order to lend it a nutrient balance is critical for having a good campaign. It is one of the practices that influences the most in the harvest’s production and quality, and must be as respectful as possible of the environment, preventing leachate and runoff.

Although the necessary macronutrients (nitrogen, potassium and phosphorus) are naturally in the soil, they will not replenish fast enough to maintain soil fertility. That is why it is necessary to make additional contributions. But which fertilizer should be used?

Based on the securities that offer organic full fertilizers compared to synthetic fertilizers and even manure (See: The benefits of 100% organic full fertilizers), before choosing one or the other soil and foliar analyses should be carried out in order to grasp the exact needs of each crop.

Not only the characteristics and composition of the substrate must be taken into account, but also the type of plant material, age, agricultural practices, water status or planting density used, among other items. It is also important the observation of the farmer on the development and evolution of plants.

In keeping with these circumstances to try to prevent nutrient deficiencies and excesses, fertilizers can be applied as efficiently as possible through its specific formulation, fractionation and / or its adaptation to the stage of the crop cycle when its availability is the most appropriate.

Fertilizers for new olive trees and vineyards

Fertilizers Organitro and Seivital K

At the current stage of the production cycle of the olive tree, it needs all the energy to develop its leaf mass, and one of the best options – due to its formula –  is full fertilizer Organitro®, which includes much nitrogen and is 100% organic. Accordingly, it is the most appropriate reference for new vines.

Its high organic matter content substantially improves the soil’s chemical, physical, and biological properties. It also increases its capacity of cationic exchange* and acts as a buffer agent to lower the tendency to sudden pH change in the soil when acidic oralkaline reaction substances are applied. It also allows the formation of organometallic complexes, thus stabilizing soil micronutrients that otherwise would not be profitable.

It is crucial to stimulate the plant metabolism and crop revitalization, especially during periods of peak nutrients demand, in order to achieve higher productivity, and references like this are essential.

Vines in production

For vines in production, with higher potassium requirements, you can use specialized solutions such as Seivital K. It is an organic fertilizer with a high percentage of this essential macronutrient, which also makes it the most appropriate when crops are into the flowering and setting periods.

Thanks to its input of organic matter and humic acids, allows farmers not only to improve soil structure by increasing cation-exchange capacity, but also boosts microbial activity and the availability of exchangeable potassium at the time it favors the transformation of this nutrient, which is included in the soil in a form that cannot be absorbed by the plant.

*Ability of soil to retain and release cations. The most important cations related to plant growth are calcium (Ca), magnesium (Mg), potassium (K), ammonium (NH4 +), sodium (Na), and hydrogen (H). The first four are nutrients directly involved in plant growth. Sodium and hydrogen have a pronounced effect on the availability of nutrients and moisture.
