Soil degradation in vegetable farming is a growing concern, and it's often the result of long-term improper agricultural practices. First, excessive use of chemical fertilizers without enough organic matter leads to soil structure deterioration. This reduces soil porosity, limits microbial activity, and causes compaction, which hinders root development and negatively affects plant growth.
Second, overuse of chemical fertilizers also increases soil salinity. As salt ions accumulate, the pH level rises, making it harder for plants to absorb water and nutrients. This stress can lead to stunted growth and even plant death.
Third, continuous cropping depletes essential trace elements like zinc, boron, molybdenum, copper, and manganese from the soil. Without proper replenishment through trace fertilizers, these deficiencies limit plant development and reduce yield quality.
Fourth, shallow soil layers due to poor tilling practices restrict root expansion. Manual planting and lack of deep plowing prevent the formation of a healthy, well-aerated soil layer, which is crucial for strong root systems.
Lastly, repeated planting of the same crops creates an environment where pests and diseases accumulate. This leads to more frequent outbreaks, increased pesticide use, and higher chances of contamination in vegetables.
To address these issues, crop rotation is highly recommended. By alternating between different vegetable types—such as melons and onions—you can break pest cycles and improve nutrient utilization. Onions, for example, take up fewer nutrients than melons, helping to balance soil fertility.
Applying organic manure is another effective strategy. It improves soil structure, enhances water retention, and promotes beneficial microbial activity. Organic matter also helps reduce salinity and supports stronger root systems.
Implementing fallow periods during off-seasons allows the soil to recover. For instance, exposing the soil to winter sun can help eliminate pathogens and restore its natural balance.
Trace element supplementation is essential, especially when deficiencies are evident. Applying base fertilizers like zinc sulfate (1–1.5 kg/acre), borax (0.3–0.5 kg/acre), ammonium molybdate (0.1–0.2 kg/acre), copper sulfate (1–2 kg/acre), and manganese sulfate (2–3 kg/acre) can help. Foliar applications are also effective, with concentrations varying by nutrient.
Finally, deep plowing at each planting season is crucial. Whether using animal-drawn plows or manual digging, this practice helps build a deeper, healthier soil layer that supports better water and nutrient retention, ultimately benefiting vegetable growth.
