The recommended rate of poultry droppings for maize can vary depending on several factors such as soil type, nutrient content of the poultry droppings, climate, and maize variety. In general, poultry droppings are a good source of nitrogen, phosphorus, and potassium, which are important nutrients for plant growth.
According to some studies, the recommended rate of poultry droppings for maize can range from 2 to 6 tons per hectare (or about 0.8 to 2.4 tons per acre), depending on the nutrient content of the droppings and the soil fertility. It is important to note that applying too much poultry droppings can result in nutrient imbalance or toxicity, which can negatively affect plant growth and yield.
It is recommended to conduct a soil test to determine the nutrient content of the soil and the appropriate rate of poultry droppings needed for maize production. Additionally, it is important to apply the poultry droppings at the right time and in the right manner to maximize their benefits and minimize their negative impacts.
