Description

A COMPOSITION FOR FERTIGATION

FIELD OF INVENTION

The present invention relates to a composition for fertigation. More particularly, the present invention relates to a composition, comprising heterocyclic nitrogen and phosphonic sequester (P₂0₅), both in soluble form, with neutralizer potassium hydroxide (KOH) or potassium chloride (KCl). The present invention also provides a process of preparation of the composition for fertigation. The heterocyclic nitrogen in soluble form helps plants to synthesize enormous amount of materials by photosynthesis and by secondary photosynthesis and biochemical reactions. Sequestering agent amino trimethylene phosphonic acid (ATMP) delivers nutrients in soluble forms to plants.

DESCRIPTION OF PRIOR ART

Fertigation is widely used in agriculture and horticulture to feed nutrients to plants through irrigation water. Uptake of nutrients by fertigation is higher than by conventional methods. Efficiency of fertilizer use through fertigation is in the range of 80-90 percent and this helps to save nutrients upto 25 percent. In fertigation, nutrient and water are applied at the root zone for greater absorption by plants. At present the fertigation segment, i.e drip, sprinkler and fogging is covered by conventional soluble fertilizer. Some of the commonly used nutrients or fertilizers applied through irrigation systems are soluble like Mono Ammonium Phosphate (MAP), Mono Potassium Phosphate (MKP), 19: 19: 19, potassium nitrate (KNO3) etc. However, Heterocyclic Nitrogen and Phosphonic Acid (phosphonics are second generation chelating agents) are not used in present fertigation.

Chelated compounds are widely used in agriculture for supplying plant with micronutrients as plant may have trouble getting the required micronutrients due to fixation and even when soil contains the required amount. Chelates such as ethylene diamine tetra acetic acid (EDTA) are commonly used. Micronutrients chelated by amino trimethylene phosphonic acid (ATMP) are taken up by the plants easily. Moreover, in soil, chelating agent is required in adequate quantity or powerful chelants in small quantities for use with microelements and calcium (Zn, Mn, Fe, Cu and Mg). Known in prior art is a mineral containing polymeric composition having high aqueous dispersibility which may be used in fertigation where minerals are applied to the soil or for emergent plants. It is important to get chelation in soil to make nutrients available to plants. Using conventional soluble and then going for chelated products in irrigation systems is a costly venture and all in one is economical, i.e. nutrients, chelants and hormones.
