The fertilizers derived from date syrup may include date sugar acids chelated to at least one metal ion useful for promoting plant growth. The date acids may be synthesized from waste or non-consumable dates. The fertilizers derived from date syrup may be synthesized by extracting date syrup from dried dates, oxidizing the date syrup to obtain date acids, and chelating the date acids to at least one metal ion. The at least one metal ion may be selected from the group consisting of potassium, calcium, magnesium, copper, iron, manganese, molybdenum, zinc, and a combination thereof.

An organic fertilizer with one or more natural ingredients is provided. The organic fertilizer includes molasses to provide additional nutrients to the soil that are readily available for plant intake such as providing sugars to increase microorganism activity. An aromatic ingredient is provided to mask the unwanted odors of other fertilizer components.

The present invention provides a method for the preparation of multi-nutrient potassic fertilizer, by recovering potassium from sugarcane molasses based alcohol distillery effluent (commonly known as spent wash). The process involves pre-treatment of spent wash to clarify the aqueous phase and utilization of the treated spent wash in production of potassic fertilizer. The present invention enables utilisation of spent wash for recovery of value-added product (viz., potash fertiliser of >99% purity) and improves ease of Zero Liquid Discharge compliance by subjecting the relatively benign process effluent to industrially practiced techniques for water recovery and salt reclamation.

An anti-caking agent for soil includes, as effective ingredients: a lignin having a molecular weight peak, as measured by GPC molecular weight analysis using a UV detector at a wavelength of 254 nm, within the molecular weight range of 10,000 to 40,000; and a diatomaceous earth. A method of improving the growth of a plant uses the above described anti-caking agent for soil. The anti-caking agent for soil has the effect of reducing the caking of soil and improving the poor growth of a plant.

Nutrient sources for a plant growth medium are disclosed. The nutrient sources include feather meal, soy meal, and optionally compost. Plant growth mediums including such nutrient sources exhibit desirable nutrient release profiles and advantageous plant growth. Methods of making and using the nutrient sources and plant growing mediums containing such nutrient sources are further disclosed.
