Mineral feeding of Actinidia (kiwi)

The articl presents the results of many years of developing a fertilization system for actinidia grown on red soil in the humid subtropical zone of Western Georgia and studying the impact of new types of complex fertilizers on the content of nutrient elements in the soil and plant, yield, and fruit quality indicators.The optimal ratio of nutrient elements in the soil has been determined under vegetation and field trials. The use of new types of complex fertilizers enhances the absorption of phosphorus from the soil by plants, increases the amount of mobile potassium, slightly changes the potential acidity of the soil, and reduces the level of soil pollution with ballast substances.The interrelationship between the main nutrient elements in the soil, which ensures increased yield and influences the structural and mechanical composition of the soil, has been studied.The optimal ratio of mineral fertilizers for young plants is double doses of nitrogen, phosphorus, and potassium.
