Which method can improve plant nutrient availability in soil?

Implementing proper tillage practices is essential for improving plant nutrient availability in soil. Tillage influences the physical properties of the soil, such as its structure and texture. When done correctly, it can enhance soil aeration, water infiltration, and root penetration, which are critical for healthy plant growth.

Proper tillage also facilitates the decomposition of organic matter, making nutrients more accessible to plants. By breaking up compacted layers and mixing in amendments, tillage can help distribute nutrients throughout the soil profile and improve its overall fertility. Additionally, it can help manage weeds and pests, which further supports nutrient availability and uptake by plants.

In contrast, over-irrigation can lead to nutrient leaching and waterlogging, reducing nutrient availability. Reducing soil organic matter negatively impacts soil health and nutrient retention, making nutrients less accessible to plants. Avoiding soil testing can result in an inadequate understanding of nutrient levels and imbalances, leading to poor fertility management decisions. Therefore, practicing proper tillage methods stands out as the most effective approach for enhancing nutrient availability in the soil.
