Organic Gardening – Manures and What Determines Their Nutrient Value

The term manure is commonly taken to mean a source of organic fertilizer in the form of excrement from farm animals, it is a lot much more. Manure from an animal source is only one of the major solutions that have been used throughout history to maintain soil fertility, offer a source of carbon, along with other constituents that have an effect on soil humus information, biological activity and soil structure. Manures from animals also have their downside, they can also be a major pollutant if not monitored in soil Go to there website.

You will find three principal types of manure used for agricultural soil management, animal, compost and plant. Manure is organic matter used as an organic fertilizer that contributes into the fertility of soil, and tilth.

Several factors determine the nutrient value of manure, type of animal, age of herd or flock, feed, feed supplements, bedding materials, method of collection, storage system, method of application, timing of application, soil texture, along with the weather. Whenever any one of these factors changes, so will the nutrient value to also change.

Animal species is what determines the type of manure. A fresh manure from most species will contain between 10 – 20 lbs of nitrogen, 5 – 10 lbs of phosphorus, and 10 – 15 lbs of potassium per ton of manure. Poultry manures however, have nitrogen and phosphorus levels, and sheep manures have higher potassium levels.

The type of feed that an animal consumes is a big factor in the nutrient content material of manure, 75 – 90 percent of the vitamins in feed is not used by animals and is excreted. Whenever you change the feed source, even seasonal changes of a pasture, the nutrient content material of manure will change. feeds that are carefully balanced to deliver exceptional nutrient use by an animal, will greatly reduce the nutrition excreted in an
animals manure.

Animal bedding materials absorb urine, and to an extent reduce nitrogen losses. Bedding materials provide a bigger benefit on changing the rate that vitamins are made offered, than for changing the nutrient articles of manure. the higher carbon content material of a manure and bedding mix makes for less vitamins and minerals to be obtainable the first year of application, but more the years following.

Collection and storage systems are two additional factors that determine manure nutrient values. Manure when uncovered to sun and wind will lose nitrogen by evaporation, and rain will leach soluble nitrogen, phosphorus, and potassium from a stockpile.
