Question
Complete the following sentences about how soil composition and pH impact plants. texture field capacity alkaline available water sulfur gravitational water permanent wilting point hygroscopic water nutrients liming organic content acidic There are three types of water that occur in the soil: gravitational water (drains through pore spaces immediately after it rains), hygroscopic water (bound to soil particles) and capillary water. Capillary water, found in the pores of soil, is the type of water that plants typically absorb through their roots. The amount of water a given area of soil retains after gravity has acted on rain water is called its (1) field capacity. This amount is chiefly determined by the _______ of the soil, though the soil's structure and _______ can also be slightly influential. When plants are unable to absorb the amount of water they need to function, the soil has reached the (2) permanent wilting point. The difference between (1) and (2) is called available water. 5oil pH is highly variable and can have a large effect on the diversity and availability of soil . For instance, in highly acidic soils nitrogen-fixing bacteria are absent, while in alkaline soils minerals such as iron and copper are often relatively unavailable. For agricultural purposes, extreme soil pH is counteracted by ______ acidic soils to make them more basic, and adding ______ to alkaline soils to make them more acidic.Explanation / Answer
Gravitational water, hygroscopic water
Field capacity, texture, organic content, permanent wilting point, available water
Nutrients, acidic, alkaline, liming, sulfur
