Collecting the dirt on soils : advancements in plot-level soil testing and implications for agricultural statistics by Gourlay, S., Aynekulu, Ermias, Shepherd, Keith D., Carletto, C.

“…Much of the current analysis on agricultural productivity is hampered by the lack of consistent, high quality data on soil health and how it is changing under past and current management. Historically, plot-level statistics derived from household surveys have relied on subjective farmer assessments of soil quality or, more recently, publicly available geospatial data. …”

Optimum sample size for determining disease severity and defoliation associated with Septoria leaf spot of blueberry by Ojiambo, P.S., Scherm, H.

“…For data summarized at the shoot level, percent defoliation increased nonlinearly (R2= 0.729, P< 0.0001, n= 224) as disease severity increased, with a rapid rise to an upper limit showing little change in defoliation above 60 spots per leaf. Variance components were calculated for disease severity to partition total variation into variation among leaves per shoot, shoots per bush, and bushes within the field. …”

Evaluation of plant-based water status indicators in mature apple trees under field conditions by Doltra, Jordi, Oncins, Jose Antonio, Bonany, Joan, Cohen, Moshe

“…Three daily measurements of stomatal conductance (g(s)) and stem water potential were made during five consecutive days in mid-September. Trunk diameter changes (TDC) were recorded by LVDT sensors, and from these measurements, maximum daily shrinkage (MDS), daily growth (DG), and cumulative growth (CG) were calculated. …”
