Nutrient unavailability, soil pathogens, and weed seeds are problems when using organic matter in soils. Too high an amount of organic matter can increase phosphorus concentrations to polluting levels. Ratios in excess of 30 to 1 for carbon and nitrogen make soils and soil food web members, such as plant roots, deficient in nitrogen.
What else can I help you with?
How can you calculate organic matter content in soil?
The amount of oxidizable organic carbon and the degree of weight loss from sustained temperatures at 680 degrees Fahrenheit (360 degrees Celsius) are ways to calculate the organic matter content in soil. The first-mentioned measure is the Walkley-Black method that employs hazardous chromic acid in soils whose organic matter measures at less than two percent. The second-mentioned measure is the Weight Loss on Ignition method whose weight loss gets correlated with oxidizable organic carbon in soils whose organic matter measures at more than six percent.
Will spraying ammonia on soil loosen it?
Spraying ammonia on soil will not loosen it. Ammonia is a compound of nitrogen and hydrogen that can add nitrogen to the soil but can also harm beneficial soil organisms if used in excess. For loosening soil, consider using methods like tilling or adding organic matter.
How are bacteria decomposers?
Using some enzymes they reduce organic matter to inorganic matter in multisteps
How can soils with poor water retention properties be improved?
In order to make a soil retain more water, you have to add a substance to it that retains more water. Typically this is done by adding organic matter, though in some situations clay can be added. The addition of composted organic matter increases the water holding capacity of soils, as well as increasing soil fertility.
What are the factors that will effect the permeability of soils?
Factors that can affect the permeability of soils include soil particle size, soil structure, soil compaction, soil porosity, and the presence of organic matter. Coarse soils with larger particles tend to have higher permeability compared to fine soils with smaller particles. Well-structured soils with larger pore spaces typically have higher permeability than poorly structured soils.
What Soil responsible for high aggregate land?
Soils high in clay content are responsible for forming high aggregates, as they have the ability to bind particles together. Clay particles create spaces for air, water, and roots to move through, improving soil structure and fertility. Proper management of these soils, such as avoiding compaction and using organic matter, can enhance aggregate stability and overall soil health.
How do soils sustain life?
Soils sustain life by providing a habitat for organisms such as plants, fungi, bacteria, and insects. They also serve as a medium for plant roots to obtain water, nutrients, and support for growth. Additionally, soils help regulate the water cycle and store carbon, playing a crucial role in nutrient cycling and ecosystem stability.
What has the author Pedro Flores written?

Why buy organic?
Organic foods are grown without using synthetic fertilizers and pesticides. Organic growers use compost and other organic matter to build up the soil and provide a wide range of nutrients, which are needed for healthy plants and are passed on to people. Organic foods are GMO free.
what process changes solar energy into organic matter so that it can be cycled through a food chain?
Photosynthesis is the process by which plants, algae, and some bacteria convert solar energy into organic matter (sugars) using carbon dioxide and water. This organic matter serves as food for other organisms in the food chain, allowing the energy to be transferred and cycled through the ecosystem.
What soil problems?
Soil problems can include issues such as soil compaction, poor drainage, erosion, nutrient depletion, and soil pH imbalance. These problems can affect the health and productivity of plants, leading to reduced growth and yield. Proper soil management techniques, such as adding organic matter, using cover crops, and adjusting pH levels, can help address these soil issues.
Paramecium feed on organic matter in a pond How does it capture food?
Paramecium capture food using its cilia, which create water currents to draw in organic matter. Once the food enters its oral groove, it is engulfed by the cell membrane and forms a food vacuole. Digestive enzymes are then secreted into the vacuole to break down the food for nourishment.
