Mechanical harvesting of leafy greens on small farms
… have been revolutionized by the advent of mechanical harvesters, but there is a disparity between available agricultural technology and the technology used in the farm equipment that is affordable for operators of small farms. The harvesting practices for salad greens from small farms is …

Green soybeans: Physical and rheological properties, optimization of harvest time, and mechanical harvesting and shelling
"Physical and rheological properties of green soybeans were measured at different stages of seed development. These properties included texture, color, size, and seed strength. Mathematical models were developed relating each property to seed development. The models were then combined to develop an …

Techniques for evaluating the behavior of apple skin under tensile loading
… there has become a dire need for equipment to mechanically harvest and handle apples. Apple growers have had trouble finding suitable labor to economically harvest their crop. Thus far, mechanical harvesting has not been very successful. One basic problem encountered by mechanical harvesting …

Application of Machine Learning and Hyperspectral Imaging in Plant Phenomics Research
… the edamame varieties that are more adaptable to mechanical harvesting and give more yield, along with understanding the physiological mechanisms for better shoot architecture traits and better yield. We used spectral signatures of different edamame at several harvesting time along with machine …

Relação entre resistência mecânica do solo à penetração e textura do solo em área de colheita mecanizada de cana-de-açúcar no litoral paraibano
… of new technologies. In this scenario the mechanical resistance to penetration comes with a parameter for assessing soil physical quality in detriment of the intensive use of agricultural machinery in particular mechanical harvesting of cane sugar combined with precision farming. The …

A hydraulic damping approach to variable stroke tree shaker design
Much interest in mechanically harvesting apples has been generated, but no completely successful system has yet been developed. Bruising of the fruit has been a prime drawback to current mechanical harvesting methods. One practical approach to mechanized apple harvesting is to shake the trunk or …

Ecological Sustainability of Winter Harvesting in the Duck Mountain Provincial Park, SK: The Effects of Skidder Traffic, Slash Loading, and Cumulative Effects on Soils and Aspen Regeneration
… of the Duck Mountain Provincial Park (DMPP), mechanical harvesting has been shown to be an effective source of disturbance to re-establish a healthy and productive forest. However, harvesting operations can result in a degree of unwanted disturbance that could threaten the success of …

Mechanization of the selective harvest of broccoli
… the selective harvest of broccoli. Selective harvesting has advantages over once-over harvesting because of greater yield and reduced handling requirements. Results of a preliminary experiment measuring broccoli stalk cutting forces indicated that the blade speed for a broccoli cutting …

The Lasting Effects of Prescribed Fire and Harvesting on Forest Floor and Soil Nutrients in the Eastern Sierra Nevada Mountains
… cause a harmful wildfire. Although these mechanical harvesting techniques are becoming more popular, little is known about their long-term effects on soil fertility, forest health, and water quality. The objective of this study was to quantify the lasting effects of prescribed fire and …

Exploring Phosphorus Dynamics in Mid-Atlantic Soils: A Multi-Scale Analysis Integrating Soil Fertility and Land Management for Environmental Sustainability
… exceed the crop's P removal needs. Moreover, mechanical harvesting efficiency was notably higher for short-statured edamame varieties (89.3%) compared to tall varieties, indicating their preference for improved harvesting. The second component examined the influence of agricultural lime on …

Dissecting the Transcriptional Regulatory Network Underlying Plant Wound Suberin Biosynthesis
… potential revenue each year. Wounding during mechanical harvesting and post-harvest handling results in tuber desiccation and provides an entry point for pathogens. Poor wound healing is the major cause of these losses. Wound tissue in potato tubers and all higher plants is comprised of a …
