Effect of drop irrigation modes on soil properties under Actinidia deliciosa plantations

Abstract

The article presents the influence of drop irrigation regimes on the mineral nutrition of actinidia plants of the industrial delicacy Hayward variety and the enzymatic activity of the soil. The most optimal irrigation mode is on reaching a pre-threshold humidity of 80% of HB. Watering at a humidity of 90% of HB has caused leaching of nitrate nitrogen. The urease enzymatic activity of the soil under the plants has increased, which increases their nitrogen nutrition.
