Potato productivity in the northeastern US has been relatively constant for over 50 years, raising questions about what factors are limiting productivity. Research was initiated in 2004 to identify key constraints to potato productivity by evaluating Status Quo (SQ), Soil Conserving (SC), and Soil Improving (SI) cropping systems under both rainfed and irrigated management, and it was found that addition of compost or irrigation substantially increased yield. In this study, we employed partial budgeting to determine cost differences and their impact on net revenue for these cropping systems. Differences in systems were primarily associated with rotation length, tillage operations, compost and application expenses, and water management practices. When compost (as composted dairy manure) was annually applied at 19 Mg·ha −1 and evaluated over the entire 3-year crop rotation cycle, the compost-amended rainfed SI system was more expensive to maintain than the irrigated SC system if compost cost exceeded $3.63 Mg . Average marketable yields were used to calculate gross and net revenue for each system. Because average potato yield for the irrigated SQ system (28.4 Mg·ha ), we were able to compare cost of irrigation versus compost for achieving comparable yield. The compost-amended SI system under rainfed management generated more net revenue from the potato crop than the irrigated SQ system when compost costs were less than $7.42 Mg . When compared to the commonly used rainfed SQ system, rainfed SI achieved higher net revenue as long as compost cost was less than $22.95 Mg . The rainfed SI system achieved higher net revenue than the irrigated SC system when compost cost was $9.43 Mg −1 or less, but generated greater net revenue than the rainfed SC system regardless of compost costs, due to substantially higher yields associated with compost amendment. This investigation demonstrates that compost is a potentially viable substitute to irrigation for potato in the northeastern US; however, such potential is highly dependent on suitable compost sources and application costs.

“…Relatively minor increases in soil water content under compost addition, compared to the control, may provide a yield benefit. DeHaan et al (1999) using potato bulk yield monitoring with global positioning system showed that a relatively small range (20 to 25% H 2 O) in soil water content (at -0.033 MPa), across commercial potato fields in Prince Edward Island, was significantly (P = 0.05, r = 0.82) related to potato tuber yield differences of 5 to 7 Mg ha -1 . The relatively small, but significant increases, in soil water content at "field capacity" in the potato phase in this study (due to compost application in the previous year), along with the other soil aeration and porosity interactions, may explain the increased potato yield above that obtained at "yield maximum with N" yield (Fig.…”

. 2004. Influence of compost on the physical properties and organic matter fractions of a fine sandy loam throughout the cycle of a potato rotation. Can. J. Soil Sci. 84: 211-218. Potato (Solanum tuberosum L.) rotations often require organic amendments to maintain or improve soil organic matter levels and soil physical properties. However, beneficial effects of compost can be modified by time of application and rotating tillage depth and intensity. This study was conducted to evaluate the effect of compost applied once at different phases in a 3-yr potato, barley (Hordeum vulgare L.), and red clover (Trifolium pretense L.) rotation on a range of soil physical properties and organic matter fractions for a Charlottetown fine sandy loam (Orthic Humo-Ferric Podzol) in Prince Edward Island. Soil samples (0-8 cm) were obtained during the second cycle of the rotation (after two compost applications) in the fifth year of the experiment. Soil properties were influenced by compost addition, time of compost addition, and crop phase. Compost-induced benefits in soil physical properties (bulk density, macro-porosity, oxygen diffusion rate, shear vane strength, water-filled pore space) were mainly expressed in the red clover phase of the rotation, where soil density was relatively high compared to the barley and potato phases, due to the absence of tillage. The soil physical parameters, however, were mainly within their established optimum ranges for this soil type. Soil water content at -0.033 MPa was increased by compost in the potato phase, compared to the control. Soil organic matter was influenced by both compost and crop C inputs. Compost increased soil particulate organic matter (POM) in the potato and barley phases. Due to differences in crop residue inputs, compost-related differences in organic matter were minimized in the red clover phase of the rotation. Compost addition increased potato tuber yield above the maximum yield obtained with nitrogen application. This "non-nitrogen" compost yield effect may be related to the slight, but significant, improvement in soil water-holding capacity. Overall, compost application in an intensive 3-yr potato rotation provided benefits for potato productivity and in both soil physical and biological properties. 211-218. Les assolements avec pomme de terre (Solanum tuberosum L.) exigent souvent des amendements organiques pour que le sol garde ou améliore la quantité de matière organique et ses propriétés physiques. Toutefois, le moment de l'application ainsi que la profondeur et l'intensité des labours peuvent modifier les avantages du compost. La présente étude devait préciser les conséquences de l'application de compost à divers moments lors d'un assolement de trois ans incluant la pomme de terre, l'orge (Hordeum vulgare L.) et le trèfle rouge (Trifolium pratense L.) sur diverses propriétés physiques du sol et sur les fractions de la matière organique dans un fin loam sablonneux Charlottetown (podzol orthique humo-ferrique) de l'Île-du-Prince-Édouard.

“…The idea is to assess the spatial variability in potato yields and relate this variability to yield limiting factors in the soil and landscape (DeHaan et al, 1999). Reports have indicated that after successful calibration of potato yield monitor; measured yields have been within 5% accuracy (DeHaan et al, 1999;Rawlins et al, 1994;Godwin and Wheeler, 1997).…”

Precision agriculture is a new and developing discipline that incorporates advanced technologies to enhance the efficiency of farm inputs in a profitable and environmentally sensible manner. Yield monitoring and variable rate application are the most widely used precision technologies. Versatile guidance systems utilizing the global positioning system (GPS) and management zone approaches are also being developed to further increase productivity by reducing error, cost, and time. These technologies provide tools to quantify and manage variability existing in fields across an array of cropping systems. A review of precision farming technologies that are currently being used in the
