Crops in acid soil demo 2017 05 09 6758

Description:

Description: English: The effect of soil acidity on different crop species. Crops (from left to right) are three different maize varieties and three different soyabean varieties. The soil in the background was limed at a rate of 10 t/ha bringing the soil pH (in salt solution) to 4.10, pH (water) to 4.72 and acid saturation to 31%. The soil in the foreground is highly weathered and naturally acid with soil pH (salt solution) of 3.79, pH (water) of 3.84, and acid saturation 75%. This was prepared as a field demonstration for the 5th International Symposium on Soil Plant Interactions at Low pH (2001). Date: 2001. Source: Own work. Author: Alandmanson.
