Abstract: The invention relates to the field of slow/controlled release fertilizer, in particular to a urea-formaldehyde-based multi-nutrient slow/controlled release fertilizer and a preparation method thereof. The urea-formaldehyde-based multi-nutrient slow/controlled release fertilizer comprises ammonium polyphosphate, inorganic silica gel and urea-formaldehyde, wherein the phosphorus-oxygen double bond of ammonium polyphosphate can at least form hydrogen bond linkage with a urea-formaldehyde molecule chain, the hydroxyl group of the inorganic silica gel can at least form hydrogen bond linkage with the urea-formaldehyde molecular chain, and ammonium polyphosphate, inorganic silica gel and urea-formaldehyde together form a hydrogen bond associated polymer network structure. The invention can prepare a urea-formaldehyde-based multi-nutrient slow/controlled release fertilizer comprising a strong hydrogen bond network structure by using a conventional aqueous solution polymerization in combination with a normal temperature extrusion granulation process, avoiding the coating process in the latter stage of the preparation of a coated fertilizer, achieving a simple and effective preparation process, and saving a lot of manpower and material resources. The urea-formaldehyde-based multi-nutrient slow/controlled release fertilizer provided by the invention can stably and continuously release nitrogen nutrient throughout the release period, thereby making up for the shortcoming of excessively long nutrient release period of the existing urea-formaldehyde fertilizers.

Abstract: A compatible combination of micron size carbon based particles along with beneficial microbial species and conventional plant nutrients into a plant or an animal food. This balanced product is a combination of nutrients and microbes, and can be applied as a suspension in water or as a slow release granule. This combination of organic plant food and fertilizer can also be applied as a foliar, as a seed coating, and as an all-in-one granule combination of nutrients and biological agents, to facilitate mineralization, nutrient availability and provide energy to the soil and plants, with a total conversion of a storable processed biomass into a precisely known quality and quantity of usable fertilizer ‘tea’ solution, with no biomass waste, odors, or crop application timing problems. The process of formulating the combination product reduces green house gas emissions by limiting mineralization and composting.

Abstract: There is disclosed a method for detecting clogging of air feed pipes, comprising air feed pipes (15), each having an outlet (13) for jetting air into a granulation section (1), and jetting nozzles (13), each situated at the center of the air outlet of a said air feed pipe for jetting a liquid of a molten raw material (e.g. molten urea), wherein, in jetting the liquid of the molten raw material from the jetting nozzles into the granulation section to carry out granulation,(a) an orifice section (14) is provided at a lower part of each of the air feed pipes (15), a section for taking up orifice rear pressure (16) is provided in each air feed pipe and is located downstream of the orifice section, and a section for taking up orifice forward pressure (17) is provided upstream of the orifice section, and(b) the pressure difference between the orifice forward pressure and the orifice rear pressure is measured, to detect clogging of the air feed pipes based on an abnormality in the pressure difference regarding the air feed pipes. There is also disclosed a granulation method, comprising monitoring the pressure difference by the above method, stopping the feed of a liquid of a molten raw material to the air feed pipe whose pressure difference is abnormal, and compensating the amount corresponding to the stoppage with the remaining function. The detection method is a method capable of detecting accurately a malfunction related to jetting of air in the granulation of urea or the like. Further, the granulation method is a granulation method wherein, accurately, in response to the occurrence of a malfunction related to the jetting of air, the feed of a raw material liquid to the malfunctioned section is stopped, and the raw material liquid to be fed to the jet nozzles having other normal air outlets is suitably increased, thereby allowing continuous operation, with the productivity before the occurrence of the malfunction kept.

Abstract: A continuous process for the production of a granulated fertilizer wherein comminuted phosphate rock, phosphoric acid and water are introduced into a pre-reactor where they are heated. The mixture is continuously withdrawn and transferred to a digester where heating is continued resulting in formation of a slurry. The slurry is continuously withdrawn and is split into two streams, one of which is recycled to either the pre-reactor or to the digester while the other stream is delivered to a granulator where it is mixed with other fertilizer ingredients and dried to form the granulated fertilizer.

Abstract: A process for direct granulation of unpurified urea phosphate from urea and merchant- or filter-grade wet-process phosphoric acid to produce a product with exceptional satisfactory physical and chemical properties for direct application to the soil or for use in production of fluid fertilizers. The process involves the utilization of sweep air in both the reactor and the granulator to remove water from the heat-sensitive urea phosphate mixture to enhance the granulation characteristics of the product. Product drying with applied heat after granulation is essentially eliminated. Moisture content of the urea phosphate is reduced to an acceptable level (about 1.0 percent) in the granulator; however, the granules are somewhat sticky. It has been found, however, that the resulting urea phosphate with about 1.0 percent moisture is less sensitive to heat than high (4 to 6 percent) moisture product. Consequently, heated air (up to about 200.degree. F.) may be applied downstream from the granulator and into the dryer chiefly for control of relative humidity of ambient air introduced therein to less than 40 percent, thereby resulting in still further water removal and curing to effect a very dry and free-flowing product. This alternative is a viable expedient in geographic areas wherein the relative humidity of ambient air is normally in the range of about 50 percent and 80 percent.
Abstract translation: 从尿素和商用或过滤级湿法磷酸直接造粒未纯化的尿素磷酸的方法，以生产具有特别令人满意的物理和化学性质的产品，用于直接施用于土壤或用于生产流体肥料。 该方法涉及在反应器和造粒机中利用吹扫空气以从热敏磷酸尿素混合物中除去水以增强产品的造粒特性。 基本上消除了造粒后用加热干燥的产品。 尿素磷酸盐的水分含量在造粒机中降低到可接受的水平（约1.0％）; 然而，颗粒有些粘稠。 然而，已经发现，具有约1.0％水分的所得尿素磷酸盐比高（4至6％）的水分产物对热敏感性差。 因此，加热空气（高达约200°F）可以从造粒机的下游施加到干燥器中，主要用于控制引入其中的环境空气的相对湿度小于40％，从而进一步进行除水和固化 以实现非常干燥和自由流动的产品。 这种替代方案是在地理区域中可行的方法，其中环境空气的相对湿度通常在约50％和80％的范围内。
