Spirulina Organic Fertilizer For Use In Agriculture for Better Yield

Increasing the productivity in agriculture has becoming the top priority for the farmers. The area under agriculture is decreasing steadily while the rise in population is increasing, resulting in an urgency to generate higher yields from available land. Farmers in order to increase productivity use chemical fertilizers or growth promoters that affect the farm ecology and environment. This results in lower yields in the preceding years. One more important fact is providing the plants with complete nutritional requirement is very important for higher yields. Currently the products available in the market are individual fertilizers or growth promoters like N-P-K, Micronutrients, Humic acid, Seaweed extract and so on. It becomes difficult and laborious for the farmers to spray all the nutrients at one time and this may result in nutritional deficiency of some elements resulting in lower yields.
Therefore it is important to provide for a complete fertilizer that has all the required ingredients while being environmentally safe that will help in increasing the yields of the farmers and cater to the world’s ever growing food requirement by increasing productivity.

The present invention meets the need by providing water soluble Spirulina Fertilizer that combines seaweed extract, amino acids, plant growth promoters, secondary nutrients, N-P-K macronutrients, micronutrients and humic acids along with Spirulina to make a complete plant fertilizer.
The said formulation consists of Spirulina powder as the main ingredient. At least one source for seaweed extract, amino acids, secondary nutrients, micronutrients, humic acids and N-P-K food grade macronutrient is provided for making the complete Spirulina fertilizer for plants.
The invention provides a water soluble powder base formulation as well as a liquid formulation to meet the requirements and acceptance of the farmers and offer the choice of formulation.
The overall Spirulina concentration in the Spirulina Fertilizer is 1% – 98% by weight in different combinations. Similarly the concentration of seaweed extract, amino acids, plant growth promoters, secondary nutrients, N-P-K macronutrients, micronutrients and humic acids are 1% -98% by weight in different combinations to offer Plant fertilizers to suit specific plant nutrient requirement of different crops.
It is also a part of the present invention to provide a food grade source of N-P-K fertilizer to make the Spirulina Fertilizer safe for environment, and farm ecology while being highly water soluble for application through foliar or drip irrigation.
In some embodiments, a liquid Spirulina fertilizer is provided wherein seaweed extract, amino acids, plant growth promoters, secondary nutrients, N-P-K macronutrients, micronutrients and humic acids are present interchangeably or all are present at various concentrations to make crop nutrition specific combinations. It also contains a biocide to prevent bacteria development in the solution and increase the shelf life of the inventive product. Other stabilizers and emulsifiers are all also present to make it easily soluble in water and maintaining the uniformity of the solution.
In other embodiments a water soluble powder Spirulina fertilizer is provided wherein seaweed extract, amino acids, plant growth promoters, secondary nutrients, N-P-K macronutrients, micronutrients and humic acids are present interchangeably or all are present at various concentrations to make crop nutrition specific combinations.
A process of providing Spirulina fertilizer to crops includes diluting the fertilizer liquid or powder with water to obtain a liquid fertilizer solution. The liquid fertilizer solution is then applied to the crops by foliar application or fertilizer application system. The Spirulina fertilizer provides nutrition to crop and promotes growth of the crop and increases yields.
