In terms of corn, balancing the number of fruit bearing plants can prevent and control cucumber blight(128 cell seedling start trays). In order to get high yield of summer maize, it is necessary to apply fertilizer well in the middle and later period, conceive ear early, and promote high yield of big ear. Good jointing fertilizer. The amount of fertilizer required is large(3.54inch plastic plant pots). Generally, when the 9-leaf stage of summer maize is fully expanded, the soil nutrients are difficult to meet the needs of corn growth.

(fabric 200 gallon grow bags wholesale suppliers usa)The seedlings should be applied late and less if they are strong, and the thin seedlings should be applied early and heavily if they are weak(128 cell seed starter trays). 15-20 kg of ammonium bicarbonate and 500-750 kg of human and animal manure should be applied per mu.
