Clay particles are able to attract cations in the soil because they
Answer Details
Clay particles have excess negative charges, which makes them able to attract cations in the soil. The negative charges on the clay particles attract positively charged cations, such as calcium, magnesium, and potassium, which are important nutrients for plant growth. The attraction between the clay particles and the cations is known as cation exchange, and it helps to hold these nutrients in the soil where they can be accessed by plant roots. This is why clay soils are often very fertile, and why adding clay to sandy soils can help to improve their fertility.
