The present invention provides a soil heavy metal curing agent for controlling accumulation of heavy metals of crops and its preparation method. The curing agent is made from the following parts of raw materials by weight: 60˜140 parts of substance containing carbon-carbon double bond; 1˜400 parts of sulfo-compound by sulfur; 50˜500 parts of organic matter by 10% water content; 0˜400 parts of water; 0˜100 parts of an initiator; 0˜200 parts of a reducer; and 0˜200 parts of a strong base. The curing agent for heavy metals in the soil according to the present invention can reduce the cadmium, lead and mercury content in the soil and further greatly reduce the roots' absorption of these heavy metals.

The invention relates to a method for producing a nitrogen-containing fertilizer from a liquid black liquor, wherein a black liquor is formed from lignocellulose-containing biomass. A majority of contained lignin constituents are decomposed into monomeric, dimeric to trimeric compounds, and at least one free alkanolamine, in particular monoethanolamine, is removed from the liquid black liquor. The black liquor is cooled to room temperature and combined with water, a defined flowable state of the black liquor being set. The flowable black liquor is supplied to a mixing device and combined with powder solids so as to form a pasty mixture which is formed into granules.

The present disclosure provides compositions comprising a ligand and a fertilizer, including kits comprising the ligand. The disclosure also provides method of growing a plant, wherein the method comprises the step of contacting the plant with a composition comprising a ligand.

Water dispersible granules are provided containing (a) an agrochemical active ingredient that is solid at 25° C., (b) a polyoxyalkylene alkyl ether phosphate or its salt, (c) at least one anionic surfactant selected from the group consisting of arylsulfonates or their formaldehyde condensates, ligninsulfonates, and polycarboxylates, and (d) lactose. The granules are water dispersible granules having good disintegrability and dispersibility in water and also having good storage stability. The water dispersible granules can be disintegrated and dispersed in a small amount of water. Accordingly, the water dispersible granules can be mixed with paste fertilizers to produce agrochemical-containing paste fertilizers, which can also be used in paddy fields and are useful water dispersible granules.

The present invention provides a composition comprising an acidified aqueous solution of (1) micro colloidal silicic acid, (2) boric acid, and (3) a water absorbing additive, having a pH value of equal to or less than 1, wherein the micro colloidal silicic acid has particle sizes in the range of 1-8 nm, especially in the range of 1.5-6 nm. The invention also provides a particulate product obtainable by the method according to claim 18, wherein the particles comprise (1) silicic acid, (2) boric acid, and (3) the water absorbing additive, and wherein at least 90% of the particles in the particulate product have particle sizes in the range of 0.3-5 μm.
