Soil Preparation and Soil Requirements of Potato
Generally we should not cultivate potatoes in the same field for two years in succession, because the soil will be depleted and the danger of disease dissemination increases significantly. A common crop rotation scheme for potato growers is “Potato – Beans- Corn - Wheat- Potato etc.” Alfalfa or other leguminous are also cultivated in soils where potatoes have just been harvested. Growing alfalfa in potato farms is very common in the United States.
Good soil preparation has been found to have a remarkable effect on product uniformity. Potato plants can grow more easily in loose, loamy soil. There are two ways to improve your soil condition. The first is adding well-rotted compost two months before planting potatoes. The second is planting a cover crop (leguminous) (as green manure) during fall and plow the plants two months before planting potatoes. If your soil is eroded from constant potato cultivation, you may have to apply both corrective actions and consult an agronomist.
Cultivating potatoes requires extensive ground preparation. The basic soil preparation for potato farming starts during the winter (December), 2-3 months before planting seeds. Farmers often plow deeply at that time, so that they get rid of weeds and rocks and the soil becomes suitable (soft, well-drained and well-aerated) to welcome the seeds. In most cases, three plowing sessions, along with frequent harrowing and rolling, are necessary before the soil reaches a suitable condition.
