The present invention provides a method for using a new liquid fertilizer comprising potassium from a potassium source selected from the group consisting of potassium acetate, potassium formate, potassium citrate, potassium succinate, potassium propionate, potassium phosphate, organic sources of potassium, animal manure, and combinations thereof, and having a slightly alkaline pH and relatively low salt index compared to other sources of potassium for liquid fertilizer products. The fertilizer composition may further comprise additives such as sulfur, zinc, boron, calcium, manganese, iron, copper, cobalt, magnesium, or a combination thereof.

A biodegradable iron-crosslinked alginate is useful as a remediation agent for environmental contaminants such as phosphate. When charged with phosphate, or other nutrients, the iron-functionalized alginate can be used as an agricultural fertilizer.

A method for preparing a fertilizer using straws and prepared straw organic fertilizer; the method includes: composting straws, spraying a compositing microbial solution containing amino acids to start decomposition of straws, and adjusting humidity of a straw compost, times of spraying a solution of product nutrients, component of the solution to obtain an up-to-standard commercial straw organic fertilizer; and keeping the composting temperature about 70° C. for long time by adjusting the turning time of the straw compost and collocation time of spraying the solution. The method is based on rich organic matters and nutrients in straws, and need for organic fertilization by soil and the like, and by improving the nutrition condition and growing condition of microorganisms of the straw compost, crop straws are directly prepared into high-quality commercial organic fertilizer in short time, so crop straws are completely utilized, and high-quality commercial organic fertilizer product is provided for fertilization.
