Abstract Applying fertilizer nitrogen (N) only when a crop response is predicted may enhance use efficiency and profitability while protecting the environment. The index at harvest (RI-harvest, ratio of maximum grain yield that plot in question) indicates actual to applied N, although it calculated after harvest. objective this study was predict RI-harvest wheat using normalized difference vege...

Pada daerah yang luas biasanya terdapat kesulitan dalam memantau fase tumbuh tanaman padi. Seiring dengan berkembangnya teknologi, salah satu alternatif dapat dilakukan untuk memperoleh data tersebut adalah menggunakan citra satelit. Fase padi diketahui menghitung indeks vegetasi berdasarkan tingkat kehijauan bantuan MODIS algoritma NDVI. Tujuan dari penelitian ini menentukan persamaan dan rent...

Aim Theoretical, experimental and observational studies have shown that biodiversity–ecosystem functioning (BEF) relationships are influenced by functional community structure through two mutually non-exclusive mechanisms: (1) the dominance effect (which relates to traits of dominant species); (2) niche partitioning [which diversity (FD)]. Although both mechanisms been studied in plant communit...

Multiple endmember spectral mixture analysis (MESMA) has been widely applied for estimating fractional land covers from remote sensing imagery. MESMA has proven effective in addressing inter-class and intra-class endmember variability by allowing pixel-specific endmember combinations. This method, however, assumes that each land cover type has an equal probability of being included in the model...

Phenology-based multi-index with the random forest (RF) algorithm can be used to overcome the shortcomings of traditional deforestation mapping that involves pixel-based classification, such as ISODATA or decision trees, and single images. The purpose of this study was to investigate methods to identify specific types of deforestation in North Korea, and to increase the accuracy of classificati...
