How to apply foliar fertilizer to grapevines? These techniques must be mastered
Spraying grapevines with foliar fertilizer gives the leaves a wide fertilizer-receiving surface, acts quickly, saves labor and fertilizer, and is a commonly used fertilization method for grapes. Generally, absorption begins 2 hours after the fertilizer solution is sprayed, and 88% of a urea solution can be absorbed within 24 hours after spraying. Spraying 0.2%-0.3% urea solution mixed with 0.1% boric acid or borax or multi-element boron fertilizer during the flowering period can...

Why is the seedling stage the key period for applying phosphate fertilizer to rapeseed?
Rapeseed is a crop with a relatively high boron requirement. When boron is deficient at the seedling stage, the root system stops growing, there are no root hairs or no lateral roots, and the growing point turns from brown to scorched and dies; applying rapeseed boron fertilizer in a timely manner plays an important role in achieving high yield and good quality in rapeseed. The specific method is: boron fertilizer applied as a base fertilizer is applied directly into the soil, and can be applied to rapeseed...
