An organic garden on a school campus. Organic horticulture is the science and art of growing fruits, vegetables, flowers, or ornamental plants by following the essential principles of organic agriculture in soil building and conservation, pest management, and heirloom variety preservation.
plant conservation and landscape restoration. [6] [7] [8] It includes the cultivation of all plants including, but not limited to: ornamental trees/shrubs/plants, fruits, vegetables, flowers, turf, nuts, seeds, herbs and other medicinal/edible plants.
The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil ...
Cover crops manage soil erosion, soil fertility, soil quality, water, weeds, pests, diseases, biodiversity and wildlife in an agroecosystem—an ecological system managed and shaped by humans. Cover crops can increase microbial activity in the soil, which has a positive effect on nitrogen availability, nitrogen uptake in target crops, and crop ...
Strip cropping helps to stop soil erosion by creating natural dams for water and preserving the strength of the soil. Certain layers of plants will absorb minerals and water from the soil more effectively than others. When water reaches the weaker soil that lacks the minerals needed to make it stronger, it normally washes it away.
[24] [25] Cleaner water through reduced nutrient and soil surface runoff can be a further advantage of agroforestry. Trees can help reduce water runoff by decreasing water flow and evaporation and thereby allowing for increased soil infiltration. [26] Compared to row-cropped fields nutrient uptake can be higher and reduce nutrient loss into ...
Intercropping involves cultivating plants possessing complementary properties that can help each other grow to optimize the use of resources including water and nutrients.
[27] [30] This is important as one of the most common errors when cultivating plants is over- and underwatering; hydroponics prevents this from occurring as large amounts of water, which may drown root systems in soil, can be made available to the plant in hydroponics, and any water not used, is drained away, recirculated, or actively aerated ...
