“…Crop rotation is an important BMP because a single crop‐type without rotation planted for multiple years can cause excessive soil erosion, loss of soil organic carbon, and degradation of overall soil productivity (Fahmy et al, 2010). The crop rotation system considered in the simulation period for this study was a 2‐yr rotation of potato followed by barley or hay (i.e., potato‐barley or potato‐hay).…”

Runoff from crop production in agricultural watersheds can cause widespread soil loss and degradation of surface water quality. Beneficial management practices (BMPs) for soil conservation are often implemented as remedial measures because BMPs can reduce soil erosion and improve water quality. However, the efficacy of BMPs may be unknown because it can be affected by many factors, such as farming practices, land-use, soil type, topography, and climatic conditions. As such, it is difficult to estimate the impacts of BMPs on water quality through field experiments alone. In this research, the Soil and Water Assessment Tool was used to estimate achievable performance targets of water quality indicators (sediment and soluble P loadings) after implementation of combinations of selected BMPs in the Black Brook Watershed in northwestern New Brunswick, Canada. Four commonly used BMPs (flow diversion terraces [FDTs], fertilizer reductions, tillage methods, and crop rotations), were considered individually and in different combinations. At the watershed level, the best achievable sediment loading was 1.9 t ha(-1) yr(-1) (89% reduction compared with default scenario), with a BMP combination of crop rotation, FDT, and no-till. The best achievable soluble P loading was 0.5 kg ha(-1) yr(-1) (62% reduction), with a BMP combination of crop rotation and FDT and fertilizer reduction. Targets estimated through nonpoint source water quality modeling can be used to evaluate BMP implementation initiatives and provide milestones for the rehabilitation of streams and rivers in agricultural regions.

“…Lynch et al [87] reported the commercial hog manuresawdust compost (CP) and pelletized poultry manure (NW) applied at 300 and 600 kg total N /ha positively affect potato tuber yield and potato plant N uptake (112 kg N /ha) under non-limiting soil moisture conditions. Fahmy et al [88] found that pulp-fiber residue compost amendment increased potato plant-available phosphorus and potassium and the tuber yield was increased under supplementary irrigation while no change was observed in a rainfed setting compared to the non-amended plot. Green manure management and the recycling of organic materials may be a valid alternative to the conventional synthetic fertilizer-based management system for sustainable potato production, sustaining tuber yield without enhancing potential environmental risks due to N leaching [89].…”

Characteristics of Organically Grown Compared to Conventionally Grown Potato and the Processed Products: A Review

Interest in organic foods is increasing at a moment when humanity is facing a range of health challenges including the concern that some conventionally produced foods may pose possible adverse effects on human and livestock health. With the increasing human population, intensive production is increasingly trending towards high-input systems that aim to close yield gaps, increase crop yields, and develop new crop varieties with higher yield potential and tolerance to biotic and abiotic stresses, all within the context of incorporating specific traits to satisfy consumer demand. Potato (Solanum tuberosum L.) is one of the most consumed foods under different cultural diets; however, its production faces some challenges related to soilborne diseases, marketable yield and quality, sugars and dry matter content of the produced tubers, tuber content in terms of nitrate, minerals, vitamins, bioactive compounds, and antioxidants, and consumer appreciation regarding the sensory characteristics of tubers and processed products. Different studies have been investigating some of these challenges, with sometimes straightforward and sometimes conflicting results. This variability in research results indicates the general non-transferability of the results from one location to another under the same management practices in addition to differences in plant material. This review compares some characteristics of raw or boiled potato and processed products from potato tubers grown organically and conventionally. Ideally, such information may be of benefit in decision making by consumers in their dietary choices, by potato growers in their selection of crop management practices, and by scientists looking at potential areas for future research on potatoes.
