Different spreader and rate controller settings (two gate heights: 17.8 and 34.9 cm four application rates: 1743, 3424, 3486, and 6848 kg/ha two correct density values: 416.5 and 480.6 kg/m3 and three incorrect density values: 352.4, 416.5, and 544.7 kg/m3) were established as treatments. Two sources of broiler litter (termed as A and B) at different moisture contents (32% and 28% w.b., respectively) and bulk densities (416.5 and 480.6 kg/m3, respectively) were acquired and used in this study. A study was conducted to understand the effect of litter bulk density on conveyor metering and spreading distribution for a spinner-disc, litter spreader. However, the high variability in physical characteristics of litter, especially moisture content and bulk density, makes it difficult to maintain accurate metering and uniform distribution during application with spinner-disc spreaders. Poultry litter is commonly land applied as an organic fertilizer on crop and pastureland. The paper concludes with an overview of required technological improvements to land application systems for all types of livestock manure. Those criteria include the maximization of nutrient recycling and of social acceptance, the protection of air, soil and water resources and of human health and safety, the control of manure application rates, and the minimization of capital and operating costs and of energy requirements. Criteria for the design of future land application systems and the improvement of existing ones are then presented. This discussion highlights the current technological shortcomings for land application systems adapted to semi-solid and solid manure. A discussion follows on land application systems for livestock manure that includes equipment for the transfer of manure from the storage facilities, equipment for transporting the manure to the application sites, and equipment for applying the manure to soil-crop systems.
The first part of this review paper addresses the large variability of the physical, chemical, and biological properties of manure and how this variability needs to be accounted for in the design and operation of land application systems and equipment. A highly valuable fertilizer and amendment for soil-crop agricultural systems when properly managed, manure can also become an important source of pollution when the management systems are deficient. The different and often highly variable biological, chemical, and physical properties of livestock manure can result in both positive and negative impacts on air, soil, water, fauna, and flora.
