How can I make my clay soil more alkaline?

If your plants have a high nitrogen requirement, simply add a slow-release nitrogen fertilizer or composted animal manure to compensate." Other experts suggest adding gypsum to clay soil to improve drainage, leach salt from the ground and add calcium to the soil. The higher the calcium level, the more acidic the soil.

Is clay soil high in pH?

Generally speaking, clay soil is not necessarily more acidic than sandy or loamy soil. "Clay" defines the soil's texture, not its acidic or alkaline pH level. However, clay soil acts acidic in a number of ways even when it is not actually acidic, and there are some cases where the two properties are connected.

How do you break down clay soil quickly?

While there are a great many organic soil amendments, for improving clay soil, you will want to use compost or materials that compost quickly. Materials that compost quickly include well-rotted manure, leaf mold, and green plants. Because clay soil can become compacted easily, place about 3 to 4 inches (7.5-10 cm.)

Is clay soil naturally acidic?

The relationship between clay soil and CEC suggests that clay soil is acidic. ... Clay soil requires fewer chemicals to lower the pH than sandy soil does, making it appear more acidic. But the amount of additives has more to do with the chemicals running through the soil than it does the pH of the soil to begin with.

Is heavy clay soil acidic or alkaline?

The pH of most clay soils will always be on the alkaline side of the scale, unlike sandy soils which tend to be more acidic. While the high pH of clay soil might be suitable for certain plant types like asters, switchgrass, and hostas, it is too alkaline for most other plants.

What is the best fertilizer for clay soil?

The best fertilizer for clay soil is organic material, such as manures, compost and moistened peat moss. Spread 2 inches of each material on the soil each fall and till to a depth of 12 inches. Till soil when it is slightly moist, but not soggy. Working wet clay soil will further compact it.

Can a plant grow in alkaline clay soil?

Most plants can't tolerate drastic changes in pH or soil conditions, so you'll want to be reasonably sure that the pH of your soil has stopped changing drastically before you plant. Acidify the soil further, if necessary. Clay is usually very alkaline to begin with.

What are the different types of alkaline soil?

The various types of alkaline soils are shown diagrammatically as under: When the soil contains excess of sodium salts and clay complex still contains exchangeable calcium, the soil is known as saline soil or white alkali or brown alkali soil. The process of accumulation of salts leading to the formation of soils is known as salinization.

Why is clay soil more acidic than sandy soil?

Clay soil has a higher CEC count than sandy soil, meaning that it has more capacity to hold hydrogen ions, but not that it necessarily holds enough hydrogen ions to make it consistently acidic. Clay soil requires fewer chemicals to lower the pH than sandy soil does, making it appear more acidic.

Why do you need to add organic material to clay soil?

Organic Content – Clay comprises very little organic material; you often need to add alterations if you wish to grow plants in clay-heavy soil. Without added organic material, clay-heavy soil typically lacks the micronutrients and nutrients essential for plant growth and photosynthesis.
