Deep Delving
Deep Delving
Considering the importance of feeding the tree in early spring, winter fertilizing prepares the fertilizer under the soil for use by the tree at the beginning of the plant’s growing season.
Fertilizers recommended for the use of deep delving for all types of trees:
- Khazra Nano Chelated Iron fertilizer (20-60g per each tree, depending on its age)
- Khazra Nano Chelated Complete Micro fertilizer (50-100g per each tree, depending on its age)
- Khazra Nano Chelated NPK 20-20-20 fertilizer (60-120g per each tree, depending on its age)
- Khazra Nano Chelated NPK 12-12-36 fertilizer (60-120g per each tree, depending on its age)
Based on the above, a fertilizer package including 1kg of Khazra Nano Chelated, 1kg of Khazra Nano Chelated Complete Micro, 2kg of Khazra Nano Chelated NPK 20-20-20, and 2kg of Khazra Nano Chelated NPK 12-12-36 for the consumption of about 15 trees would be enough.
The best time for deep delving is from the time of leaf fall to the end of March and the swelling of the buds so that the deep delving is exposed to moisture. It must be noted that the deep delving is located in the water bath, and the water completely covers the area around and on the hole. In addition, the depth of the holes should be 50cm so that the fertilizer inside the holes does not fall out during shoveling. The best position for deep delving is the shade of one-third of the tree, where the thin and absorbing roots are located.
