The invention relates to the field of controlled release fertilizer technology, and in particular to a special film-coated controlled release fertilizer for peanut in a high yield field, which comprises an outer layer, an intermediate layer and an inner layer, integrates the ingredients for disease and pest control, chemical control, growth promotion and premature senescence prevention, controls the release period, improves the fertilization efficiency without the need of top application throughout the growth period, saves labor cost, and has positive effects on improving peanut yield and quality.

A soil enhancement fertilizer composition that is delivered in a water-soluble pouch. The pouch contains specially composted and pulverized camelid manure, Mycorrhizal fungi, and yucca powder. The pouch is dissolved in water and stirred to release its contents and then the solution is poured on the soil and/or applied to the leaves of both indoor or outdoor container plants.

A method for producing soil amendment is disclosed. The method comprising: In the first step, different parts of a mesquite tree are collected. The collected parts comprises leaves, trunk, beans, mistletoe, roots and branches. In the second step, the collected parts are organized based on nutrient level. In the third step, the collected parts are dried. In the fourth step, the dried parts are milled to obtain a powder material of desired size. The powder material obtained is applied to a soil to improve the physical constitution of the soil.

Provided are a biological floc, a process for the preparation thereof and uses thereof in aquaculture, water purification, industrial water treatment, soil remediation and improvement, and sludge innocent treatment, wherein the biofloc comprises decomposed straw powder, a first microbial agent, a nitrifying bacteria and a denitrifying bacteria, wherein the first microbial inoculant comprises Bacillus subtilis and selective actinomycetes. The process for the preparation of the biological floc comprises firstly adding the microbial agent to the decomposed straw powder, and then successively adding the nitrifying bacteria and the denitrifying bacteria. Further provided is an organic bacterial fertilizer comprising sludge, a biological floc and fermenting bacteria.

An aqueous composition which contains (a) one or more alkyl glucamides of the formula (I), wherein R1 represents a linear or branched alkyl group having 5 to 9 carbon atoms, R2 represents an alkyl group having 1 to 3 carbon atoms, and (b) water, is suitable for improving soil humidification. ##STR00001##

The present invention relates to a method for applying biochar to turf and landscape to allow the turf and landscape to be effectively maintained under reduced water and/or reduced fertilizer applications.

A composition including a liquid microbial mixture and a gemstone elixir. The composition is applied to soil of a plant to increase the health of the plant.

A growing medium comprising fibrous tree bark and fibrous wood components, wherein the fibers of the growing medium have an average length to width ratio, such that the growing medium has a dry bulk density of about 60 kg/m.sup.3 or lower and wet bulk density of about 120 kg/m.sup.3 or lower.

A heavy metal cadmium deactivator for activating the activity of sulfur-reducing bacteria in rice field soil, and an application thereof. The deactivator is constituted by electron shuttles alone or electron shuttles and electron donors, but cannot be constituted by electron donors alone. The mass ratio of the electron donors to the electron shuttles is (1:3)-(1:8). Also, a heavy metal cadmium deactivating method for activating the activity of microorganisms in rice field soil, such as sulfur-reducing bacteria. By applying the functional deactivator to rice field soil, the activity of microorganisms, such as sulfur-reducing bacteria, can be activated, thereby accelerating the reduction process of sulfur and iron in soil to facilitate the fixation of cadmium; cadmium adsorption and accumulation in rice is reduced to achieve secure production in fields moderately or lightly polluted by cadmium.

Natural biomineral fertilizers for sustainable farming are produced in an environmentally sound manner from mine waste. Finely divided mine waste and process tailings serve as a novel source of rock powder for use as fertilizer. Mine waste and process tailings may be treated with non-toxic chemicals to selectively remove certain unwanted elements such as mercury. Solid and liquid fertilizers are also obtained by digesting mine waste and process tailings in combination with bio-waste plus selected bacteria under anaerobic conditions. Anaerobic digestion also generates methane gas for use as fuel for generating electricity or for process heating.
