What are the best practices for soil preparation and management in horticulture crops, and how do they differ from those used in field crops?
Soil preparation and management are essential factors that influence the growth and yield of horticultural crops. Unlike field crops, horticultural crops are typically grown on a smaller scale and in more intensive systems, such as greenhouses, high tunnels, or raised beds. Therefore, the best practices for soil preparation and management in horticultural crops can differ from those used in field crops. Here are some guidelines to follow:
In summary, horticultural crops have unique soil preparation and management requirements due to their intensive cultivation methods and higher nutrient demands. Soil testing, organic matter additions, pH management, precise irrigation, crop rotation, and mulching are some of the best practices that can help to optimize crop growth and yield.
The best management practices include: 1- adequate greenhouse site selection; 2- appropriate greenhouse design and cover; 3- choice of the right cultivar and production/acquisition of clean and vigorous planting material; 4- adapted greenhouse production technology. The soil health foundation consists of five principles: 1) Soil armor; 2) minimizing soil disturbance; 3) plant diversity; 4) continual live plant/foot; and 5) livestock integration. These principles are intended to be applied in a systems approach, maximizing the soil building impact. Horticultural Management is a customizable service that includes weeding, scratching of mulch, hand pruning, insect and disease scouting, plant diagnostics, plant division, removal, and replacement, seasonal color. Using reduced tillage practices will protect the soil surface, which decreases soil erosion and soil compaction, and decreases the loss of organic matter. Reduction in tillage also decreases the potential for destroying soil structure. Soil management is the application of operations, practices, and treatments to protect soil and enhance its performance. It includes soil conservation, soil amendment, and optimal soil health. Soils supply the essential nutrients, water, oxygen and root support that our food-producing plants need to grow and flourish. They also serve as a buffer to protect delicate plant roots from drastic fluctuations in temperature. The purpose of land preparation is to provide the necessary soil conditions which will enhance the successful establishment of the young offshoots or the tissue culture plants received from the nursery. Horticultural crops are adapted to a wide range of soil types at times with specific requirements. Soils particle types include clay 0.002 mm or less, silt 0.05 to 0.002 mm and sand 0.05 mm or above. The most important aspect in agricultural process is to loosen the topsoil. The loosened soil helps in the growth of earthworm and soil microbes. These organisms add humus to the soil and are friendly to farmers. Plants absorb water, minerals, nutrients and air from the soil through their roots. BMPs are primarily used to modify land management practices on croplands, specifically those focused on reducing erosion and nutrient runoff. These practices can help to directly protect drinking supplies, as well as help to protect animal habitat, fisheries and agricultural uses such as irrigation and stock watering.
