Saline land can grow potatoes?
Growth of potato tubers requires sandy soils and light sandy loam with deep soil, loose soil, good ventilation, and moderate water retention. Potatoes have acid resistance, but their ability to resist alkali is very weak. The range of pH for soil pH is between pH 4.8 and 7.5, and pH 5.5-6.0 is most suitable. Different varieties of potato have different salinization abilities. Normally, when the soil content in the arable layer is less than 0.25%, it can grow normally. Above pH 8.0, organic fertilizers should be added to reduce the harm of alkali to potatoes. Alkaline soil cultivation Potatoes Avoid alkaline fertilizers, such as superphosphate, ammonium sulfate, ammonium nitrate, gypsum powder, etc. Acid fertilizers should be applied.
