- Organic matter, such as compost, is crucial for soil structure—it ensures good air circulation prevents mold, and helps create a balance among soil types, whether clay or sand. It introduces beneficial soil microbes, fights off disease-causing organisms, and helps to retain moisture and nutrients.

Jan 12, 2024 · Mulch is a layer of organic material spread on top of the soil to help it retain moisture, suppress weeds, and improve its quality. Materials commonly used for mulching include straw, wood chips, grass clippings, and leaves.

Soil Structure: The arrangement of the primary soil particles into clusters or masses called aggregates. Primary Soil Particle: Mineral particles sizes including sand (0.05 to 2 mm), silt (0.002 to 0.05 mm), and clay (<0.002 mm.) Soil Porosity: The ratio of the volume that is not occupied by soil particles to the bulk volume of the soil is called s...
Of equal importance are the quantitative aspects of the soil as a habitat for plant roots. It is necessary that nutrients, air, and water are present in optimum concentrations for normal root development and plant growth. It is also necessary that enough of them be present throughout the growing season to meet plant needs. The depth of soil availab...
There are 20 essential chemical elements (plant nutrients) known to be required for normal vegetable growth. These elements can be supplied by either organic or commercial inorganic fertilizers. Carbon, hydrogen, and oxygen from air and water, and nitrogen from organic and inorganic sources are four plant nutrients which make up 95% of plant solids...
Soil pH indicates the hydrogen ion activity of soil solution or growth media. The number expresses the degree of acidity or alkalinity in terms similar to the way heat and cold are expressed in degrees of Centigrade or Fahrenheit. The scale for measuring acidity or alkalinity contains 14 levels known as pH units (Figure III-1). It is centered on pH...
Fertilizer bags are labeled with at least three numbers. These numbers list the percentage of nitrogen (N), available phosphate (as P2O5) and soluble potash (as K2O). These numbers represent nitrogen, phosphorous and potassium, commonly referred to as N-P-K. However, these elements are symbolically represented as N-P2O5-K2O. For example, if we have...
A fertilizer is said to be complete when it contains the major nutrients, nitrogen, phosphorus and potassium. The manufacturers of commercial fertilizers are required to state the analysis (amounts of these nutrients) on the container and guarantee the analysis. Examples of commonly used fertilizers are 13-13-13, 16-6-12 and 10-20-10. An incomplete...
A soil test should be performed before the purchase of any “special purpose” fertilizers. It is not possible to make a blanket statement that one fertilizer is best for vegetables in every area of the state. It is true that different vegetables use different nutrients at different rates. The unknown is the reserve of nutrients already in your soil....
Vegetable plants take up nutrients continuously. It is beneficial to provide them with a balance of nutrients throughout their growth. At times, the most efficient way to achieve this is to apply slow release fertilizers which are designed to release nutrients over a relatively long period of time. Slow release fertilizers contain one or more plant...
Different formulations of fertilizers are made to meet the needs of different situations. All formulations must give the amount of nutrients, and it may tell how quickly a nutrient is available. Some formulations available to the homeowner include water soluble powders, slow release pellets, liquids, and granular materials. Table III-3. Approximate...
Soil type dictates the frequency of fertilizer application. Sandy soils require more frequent applications and lower amounts of nitrogen and other nutrients than do clay type soils. Other factors affecting application frequency include the crop being grown and its intended use, the frequency and amount of nitrogen or water applied, and type of fert...
- Loam Soil. Loam soil is an even mix of sand, silt, and clay, with the ideal combination being 40% sand, 40% silt, and 20% clay. By mixing them together, each component lends the soil their advantages while lessening the impact of their disadvantages.
- Clay Soil. Clay soil is soil that is made with 50% or more clay. It’s sticky when wet and rock hard when dry. Just think about it in terms of pottery – you wet the clay to make it malleable, then it dries into a hard substance.
- Sandy Soil. Sandy soil is mostly sand particles. It feels gritty to the touch. Because sand particles don’t absorb water but create a lot of space in between for water to move, sandy soil drains quickly and nutrients wash away.
- Silty Soil. Silt is between sand and clay in terms of particle size, and it’s mostly composed of quartz. Silty soil is comprised of at least 80% silt. When dry, silty soil feels like flour.
Add Organic Matter for Soil Health. All clay soils are deficient in organic matter, and especially so on the Edwards Plateau. But the trick is not to go overboard. Your garden soil should contain at least 30% by volume of real soil. This mineralized content is vital for plant health.
Feb 10, 2022 · The idea of using organic amendments in soils to increase productivity has a long and proven history worldwide. The practice increases available food, improves the environment, and recovers value from materials that might otherwise pose a disposal problem.
Apr 22, 2022 · Soil is a layer of unconsolidated (i.e., loose) mineral and/or organic material. Soil is nearest to the Earth's surface in terrestrial areas (not covered by water). Soil makes up a very small percentage of the Earth's crust.
