Yellow or brown powder;
pH value of 1% solution is 2.5-3.5;
Water solubility at 20℃is 150g /l.
A stable water soluble metal chelate, mainly used in agriculture and horticulture in soil, hydroponics or as foliar fertilizer.
Can prevent and cure the iron-deficiency. Iron is an essential microelement for the growth of plants.
Has the best characteristics of stability from photo degradation, pH, next to neutrality, and is without any phototoxic effects. The efficiency is increased when used in a mixture with products that contain amino acids.
Application DTPA-Fe11 is quite stable with the chemical properties, it’s hard to oxidize and deoxidized. And can be mixed with phosphate fertilizer and carbonate fertilizer and made into nutrient fluid. Plus it can use together with many weedicides and pesticides. It has no causticity, so it won’t burn the foliar or make the root withered. And it can quickly solute in hard water and cold water without water in soluble matter, so it’s very suitable for modern agricultural nutrition cultivation system. Dosage and application process: 1. Foliar spraying: dilute 800-1000 times, then spray directly on the foliar, every 10-15 days, when spray together with other micronutrient fertilizer, we should dilute according times, such as 1000-1500 time, in case of the over-absorbing of the microelement. 2. Water irrigation: Dilute 1200-1500 times when continuous irrigation or drip irrigation, dilute 800 times when discontinuous irrigation or drip irrigation. 3. Soil irrigation: 30 grams/m3 soil in nursery soil condition; 60 grams/ m3 soil in potting soil condition; 7-10 grams/ m3 soil in field soil condition, and it’s not appropriate to use in strong alkaline soil.
