Processes and apparatus are provided for recovery of dissolved species from wastewater streams, in the form of precipitates sized by elutriation. The processes may for example be controlled so that the recovered sized solids are in the form of relatively insoluble plant nutrients, such as struvite. The extracted nutrients may for example include solid species of phosphorus, and/or nitrogen, and/or potassium.

A biofertilizer is disclosed that include specific formulations of algae biomass and a mycorrhizal fungus. This biofertilizer may be a useful way of utilizing algae biomass created for carbon sequestration purposes for a productive agricultural purpose. The combination of algae biomass and mycorrhizal fungus may provide advantageous effects to a crop, as the algae may be a nutrient source for both the crop itself and also for the mycorrhizal fungus that allows the fungus to grow and form a mycorrhizal relationship with the root system of the crop. The biofertilizer may be pelletized with rice hull filler and have a specific range of moisture content, so as to be compatible to agricultural fertilizer delivery equipment. Methods of manufacturing the pelletize biofertilizer are also provided.

The present invention relates to a method for fertilizing corn in a semi-humid region for one time, and belongs to the field of agricultural fertilization. The method adopts a corn seeding and fertilizing combined machine to sow and fertilize for one time in a semi-humid region. The method realizes nutrient supply throughout the growth of corn without performing top dressing in a later stage. The method improves fertilizer utilization, saves labor cost and improves production and income. The present invention effectively improves ventilation and light transmission conditions in the corn field, eliminates the effect of a stubble of a preceding crop on the emergence of corn, improves uniformity, and reduces nutrient loss.

A one-off fertilization method suitable for winter wheat in areas with less rainfall in spring includes the following steps: (1) carrying out, on a flat wheat block which is suitable for mechanized operations and after the harvest of preceding crops, a deep ploughing or a subsoiling in combination with a rotary tillage and a one-off fertilization for land preparation, without involving any top dressing in a later stage; and (2) carrying out a seeding operation by a wheat seeder, wherein for nitrogen fertilizer, according to the nitrogen release period of a controlled-release nitrogen fertilizer, one of the following application modes is determined: applying a polyurethane-coated controlled-release nitrogen fertilizer alone or a water-based resin-coated controlled-release nitrogen fertilizer special for winter wheat alone; or applying a water-based resin-coated controlled-release nitrogen fertilizer special for winter wheat in combination with 20% to 30% of a polyurethane-coated controlled-release nitrogen fertilizer.
