Rotational and cover crop determinants of soil structural stability and carbon in a potato system
Understanding processes that ameliorate structural degradation in sandy soils is particularly important in intensively managed potato (Solanum tuberosum L.) systems. Seven 2-yr potato rotation systems were evaluated over 3 yr in an irrigated field trial comparing winter management systems bare (B) and cover crops: rye (Secale cereale L.; R), rye-hairy vetch (Vicia villosa Roth; RV) mixture and ...

Effectiveness and efficacy of conservation options after potato harvest
Soil erosion and phosphorus (P) runoff can be severe in potato production systems in the Northeast USA, which are characterized by intensive tillage, minimal ground cover, low crop residue return, and steep slopes. We used rainfall simulators in the greenhouse and field to assess sediment and P movement associated with two conservation practices: straw mulching and application of polyacrylamide ...

Organic amendment history and crop rotation effects on soil Nitrogen mineralization potential and soil Nitrogen supply in a potato cropping system
Crop management practices influence readily and potentially available N in soil. In this study, we evaluated the effects of organic amendment history and crop rotation on potentially mineralizable N (N0), mineralizable N pools, and field estimates of soil N supply in potato (Solanum tuberosum L.) production, and evaluated a suite of N availability measures to detect changes in these parameters. ...

How to get seed rates spot on for target market and harvest scheduling
Potato agronomy is complex and requires a lot of planning, monitoring and evaluation throughout the production process. CPM finds out how digital agronomy tool Crop4Sight can help in all three areas as preparation for the 2023 season gathers paceIf you fail to prepare, you prepare to fail – an adage that is very relevant when thinking about potato crop establishment, with half the agronomy done ...

Focus on taste and quality at Flevostar Potato - Case Study
Flevostar Potato's sorting line In August DT Dijkstra supplied a Sorting line with RT-2/5 sorting machine with hydraulic screen clamping system at Flevostar Potato in Dronten. This makes the delivery of the 1000th sorting machine a fact. Flevostar Dronten has been packaging and marketing potatoes for 25 years. In addition to the table potato and export market, the new company Flevostar ...

Tillage and fertilizer effects on yield, profitability, and risk in a corn-wheat-potato-wheat rotation
Reduced tillage results in lower production costs and thus may have economic advantages for farmers. However, yield penalties, specific yield risks, or higher nutrient requirements may counteract the positive effects of reduced tillage. This study investigates long-term tillage effects (moldboard plow, and deep and shallow chisel plow) and their interactions with N fertilizer input on yields and ...

Nitrate leaching from a potato field using adaptive network-based fuzzy inference system
The conventional methods of application of nitrogen fertilizers might be responsible for the increased nitrate concentration in groundwater of areas dominated by irrigated agriculture. Appropriate water and nutrient management strategies are required to minimize groundwater pollution and to maximize nutrient use efficiency and production. Design and operation of a drip fertigation system ...

PEWE Oregon Potato Case Study
Facility Background Out with the old and in with the new! Oregon Potato production capacity had overrun their worn out existing wastewater treatment DAF unit. It had been installed years before and soon was over-loaded and needing replacement aeration pumps regularly while the manual controls were a maintenance nightmare. To discharge water the facility needed to meet permit guidelines for TSS, ...

Possibilities for Future EC Environmental Policy on Plant Protection Products
Abstract This report presents the results of a study to examine and evaluate the economic, environmental and social benefits of plant protection products (PPPs) in agriculture with the main emphasis on the economic aspects. The approach followed was to carry out four case studies - each covering a single crop in a specific region of major production-comparing standard, integrated and organic ...
