March. Late in the month Until mid-April Ten-day period 20 Multiple days This is precisely the critical period for apple trees to develop roots and sprout new buds. After a winter of rest, the trees have begun gradually resuming their growth. To prevent deficiencies in trace and minor elements, Apply supplemental fertilizer in a timely manner. As Nitrogen, potassium, phosphorus, calcium, magnesium, zinc, and boron fertilizers, Possible Supplement tree nutrients to enhance the tree. Body length Trend. According to the survey, growers generally... To think that In spring, topdressing with ammonium nitrate calcium is more effective than using urea. Applying nitrate-based fertilizers helps apple buds develop robustly and fully. Leaf blade Thickened. According to Distributor Reflect, Farmers show a strong willingness to purchase ammonium nitrate calcium in the spring, but... The market is flooded with counterfeit and substandard products that pass off inferior goods as high-quality ones, disrupting the market with their low prices.

Nitrogen Association Calcium-Magnesium Nitrate Fertilizer Branch Provide ( Member Unit: Shanxi Sanxi Chemical Co., Ltd. Product), name Amino acid-based medium-element water-soluble fertilizer, with main ingredients including calcium magnesium nitrate, boron, and zinc; also known as... “ Abundant fruits and vegetables ”。

This fertilizer performed well in last year’s apple trial, effectively preventing the occurrence of bitter pit disease in apples and enhancing the thickness, luster, and photosynthetic capacity of apple leaves in the later growth stage. This year, we are conducting another demonstration trial to further validate the efficacy of calcium magnesium nitrate fertilizer.

The Henan Science and Technology Small Courtyard team distributed a series of experimental and demonstration calcium magnesium nitrate fertilizers to farmers.

Farmers apply the series of calcium magnesium nitrate fertilizers.
