TLDR
The yield variables and leaf nutrients that were found related showed spatial dependence without random distribution and Nutritional imbalance was detected in the studied coffee crop expressed by the deficiency or excess of some nutrients in the plant tissue.
Abstract
The aim of this study was to model the spatial variability of the nutritional status of arabic coffee using leaf macro and micronutrient contents and relate it to drop in bean yield, bark percentage and crop yield. The experiment was conducted in a plantation of arabic coffee variety Catuai located in the Zona da Mata of Minas Gerais State. Leaf nutrient contents, cherry coffee production, drop in bean yield, yield of benefited coffee and bark percentage were determined. Data were analyzed using classical statistical methods to find the relationship between nutrients and yield variables and then examined by geostatistical analysis. The yield variables and leaf nutrients that were found related showed spatial dependence without random distribution. Nutritional imbalance was detected in the studied coffee crop expressed by the deficiency or excess of some nutrients in the plant tissue. Ca provided the smallest drop in bean yield while the leaf contents of B and Zn had an opposite effect on the production and yield of coffee.

Modeling land suitability for Coffea arabica L. in Central America

TL;DR: The results show that even without the use of coffee maps as input, ALECA accurately scores the suitability of actual coffee areas for coffee production as higher than that non-coffee areas, and can accurately predict the known order of quality of coffee reference zones in Central America.

DRIS and geostatistics indices for nutritional diagnosis and enhanced yield of fertirrigated acai palm

TL;DR: Assessment of the nutritional status of fertigated Açaí palm by the Index called Diagnosis and Recommendation Integrated System (DRIS), as well as the spatial variability of this Index and its productivity, found that N and S were well balanced, whereas Mn, Ca and B were the nutrients with the highest frequency of deficiency.

Field-scale variability of soil properties in central iowa soils

TL;DR: In this paper, field-scale distributions and spatial trends for 28 different soil parameters at two sites within a watershed in central Iowa were investigated using semivariograms and the ratio of nugget to total semivariance, expressed as a percentage, was used to classify spatial dependence.
