The present invention relates to a liquid composition comprising living green microalgae for improving plant growth. The liquid composition is prepared by growing green microalgae at a pH of 10-12 in the presence of hydrogen carbonate as the inorganic carbon source. The liquid composition may be stored at 4 to 25 degrees C. until use. The liquid composition may be used to improve fertilizers.

Disclosed are a fertilizer composition containing a carbohydrate and phosphorus and a preparation method and use thereof, which belong to the technical field of agriculture. The fertilizer composition has a mass ratio of carbon to phosphorus of 1-15:1, and is divided into a low-carbon fertilizer composition (with a carbon-to-phosphorus ratio of 1-4:1) and a high-carbon fertilizer composition (with a carbon-to-phosphorus ratio of 4-15:1).

The present invention relates to methods for improving the compatibility of crop protection formulations and tank mix applications with liquid fertilizers by (i) building a chelating agent into a crop protection formulation, or (ii) adding a chelating agent when mixing the crop protection formulation with the liquid fertilizer.

The present invention is located in the field of industrial biotechnology and sustainable agriculture, referring to a process of renewable origin for the production of fertilizer from by-products of animal origin, with an innovative raw material, animal blood in natura. The invention aims at the use of raw materials such as animal blood, both in natura form and in the form of blood meal, also considering a synergistic mixture of blood meal with in natura blood, to obtain fertilizers with innovative characteristics. The synergy promoted by the stages of the developed process, combined with the qualities of the selected raw materials, promoted the development of products with high levels of free natural amino acids, total organic carbon and organic matter. The developed fertilizer product can be applied in liquid form, as a liquid fertilizer, both in soil and in foliar form, as well as in solid form, after the introduction of a drying step at the end of processing. The product adds, depending on the chemical composition obtained, both fertilizer and soil conditioning agent characteristics. The invention results in sustainable products with high added value.

There is disclosed a method of producing a soil remediant from liquid organic waste material in which the liquid organic waste material is concurrently pasteurised and digested by thermophilic aerobic digestion in the liquid phase in a single digester vessel. The organic waste material in the digester is maintained continuously at a temperature of at least 70° C. for at least an hour and the liquid organic waste material comprises at least 70% water and can be pumped. After a period of at least an hour a small amount of pasteurised organic waste material is removed and a corresponding amount of fresh organic waste material is added to the single digester vessel such that the temperature is maintained in a comfort zone of the thermophilic bacteria. In a preferred embodiment the thermophilic aerobic digestion is facilitated by micro-organisms including crenarchaeota. The liquid organic waste material can be combined with a microporous adsorbent. Also disclosed is a soil remediant comprising a microporous adsorbent and liquid organic waste material from the novel method. The microporous adsorbent may be a volcaniclastic sedimentary rock or diatomite or of vegetable origin such as biochar. The microporous adsorbent may be a powder or a granular material and may have particle sizes up to 2000 microns.
