Liquid and powder fertilisers for fertigation
Biokimia’s “Fertilisers for fertigation” enrich the soil with nutrients for ready uptake due to the carefully studied formulations with different ratio and solutions according to the specific crop, variety, nutritional needs of the phenological phases of the crops to be treated, as well as taking into consideration the different soil characteristics of the cultivated soils and varied climactic conditions. This category of fertilisers include selected and extremely pure raw materials, highly soluble to improve nutrient assimilation. The “liquid” formulations are stable and effective, by fertigation system either in drip irrigation or by direct soil application with liquid spreaders or soil herbicides tanks.
Water is the most effective vehicle for conveying nutrients to plants, so liquid or water soluble fertiliser applications assure higher production with superior qualitative characteristics, in comparison to crops treated with direct granular soil applications with traditional mineral fertilisers. There is no complete certainty on which is the best method for fertilising soil and nourishing plants as there are many unforeseen circumstances which could hamper the follow up results of the fertilising programmes. That is why the best solution from an environmental (less impact), agronomical (productivity and soil structure maintenance), and economical (better value for money) point of view, could be to provide a complete programme where all fertilising product categories are included, both by foliar and direct soil applications, reducing unit quantities and exploiting the synergy of different applications. The best advise is to try not to use products separately because plants uptake, even in different proportions during the various phases, all elements simultaneously. In fact, the plant needs all nutrients together with water, light and air for its metabolism. NPK or NP, NK, PK water soluble with magnesium and micro nutrients are preferable, with added calcium based products because they already have all the necessary correctly proportioned nutrients. Mixed raw materials can also be used, but the advantage of water soluble NPKs is that they have more ingredients with a variety of numerous raw materials, so it is possible to achieve better results instead of using only one or two single nutrients. In combination co-formulants are added (they assist, protect and transport the nutrients) with magnesium and micro nutrient supplements as support applications. Biokimia water soluble NPK fertilisers by fertigation are in four grades: Waterfert and Easyfert, for normal soil conditions and Acidfert and Challenger, for acidifying soils with a sub-alkaline and alkaline pH, some of the grades even contain calcium, notoriously non-compatible nor mixable with all forms of phosphorous. Biokimia water soluble NPK fertilisers by fertigation release nutrients directly in the solution circulating in the soil, they interact with the cationic and anionic exchange by enriching them.
Soaked plant roots can promptly uptake the nutrients. In comparison, traditional granular mineral fertilisers can only integrate nutrients reserves in the soil and the nutrients will only be ready for uptake after the microbiological action of the micro organisms make them available to the plant.
