ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an organic fertilizer and a method of application of the same.
BACKGROUND OF THE INVENTION
Care is required in handling and applying chemical fertilizers in order to avoid environmental damage, poisoning of wildlife and chemical induced illness to agricultural workers. There are well documented instances in which the requisite care was not exercised, with disastrous results. As a result, there is a movement toward organic fertilizers.
Two common forms of organic fertilizer are manure and plant matter compost. Both are difficult to handle. A further inherent disadvantage with manure is that it tends to be host to weed seeds.
SUMMARY OF THE INVENTION
What is required is an alternative form of organic fertilizer and a convenient method of applying the same.
According to the present invention there is provided a method of application of organic fertilizer. In accordance with the teachings of this method plant matter is dehydrated and pelletized to form fertilizer pellets. The fertilizer pellets are then spread on soil. When the fertilizer pellets are hydrated, the fertilizer pellets release nutrients into the soil.
The method of application of organic fertilizer, as described above, has numerous advantages. Pelletized plant matter is easy to handle. The pellets are not hazardous to wildlife; wildlife can eat them and not be harmed. The pellets will not “burn” or in any way harm the soil, even if applied excessively. When water is added the pellets expand and fall apart. As will hereinafter be documented, the pellets contain a concentration of nutrients, in greater quantities than plant matter compost.
Although beneficial results may be obtained through the use of the invention, as described above, even more beneficial results may be obtained when the plant matter is blended, either before or after dehydration and pelletization, to provide a blend of plant matter that has nutrients particularly suited for a desired application.
