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 substrate and a slurry for erosion control are disclosed. The substrate includes mulch and a cover composition including bentonite clay and cellulosic water dispersible polymer or starch. Other desired optional ingredients may also be included. Methods of controlling or reducing erosion control are also disclosed.

The present invention provides a soil heavy metal curing agent for controlling accumulation of heavy metals of crops and its preparation method. The curing agent is made from the following parts of raw materials by weight: 60˜140 parts of substance containing carbon-carbon double bond; 1˜400 parts of sulfo-compound by sulfur; 50˜500 parts of organic matter by 10% water content; 0˜400 parts of water; 0˜100 parts of an initiator; 0˜200 parts of a reducer; and 0˜200 parts of a strong base. The curing agent for heavy metals in the soil according to the present invention can reduce the cadmium, lead and mercury content in the soil and further greatly reduce the roots' absorption of these heavy metals.

A method for making a growing medium includes a step of combining tree bark and/or wood components together to form an initial composition; heating the initial composition to a temperature greater than about 149 C. under steam in a pressurized vessel; processing the initial composition through a refiner with a plurality of opposing disks to obtain the fibrous growing medium, the refiner separating fibers from each other; wherein the growing medium has total porosity of 88 volume % or more.

Improved, low-cost agricultural products are provided comprising respective amounts of humic acid and a polyanionic polymer. The products may be mixed with or applied to fertilizers to enhance plant uptake of nutrients. The polyanionic polymer preferably includes maleic and itaconic repeat units, and optionally sulfonate repeat units.

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 method for preparing an organic complex microelement fertilizer for engineering wound soil remediation includes compounding chitosan oligosaccharide or/and earthworm dung or/and silkworm sand, water or/and hydrogen peroxide, an organic complex trace element solution, polyethylene glycol octyl phenyl ether, and polysorbate under certain conditions. The present invention can significantly improve physical and chemical properties of engineering wounds, enhance effectiveness of trace elements in soil, and prevent plant physiological diseases due to lack of trace elements, and promote plant growth and development.

The present disclosure relates to an additive for soil conditioning and an agricultural composition comprising additive and plant growth regulator. The additive comprises a mixture of esters of fatty acids and an emulsifying agent. The additive of the present disclosure can be used in the conditioning of the soil which results in improvement in plant growth. The agricultural composition of the present disclosure can be used for improving soil condition and promoting plant growth.

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.

Biochars and methods for treating biochars are provided that are useful in various applications, including, but not limited to, applications related to the raising, care, maintenance, disease prevention, disease treatment and odor control of animals.
