“…The other reasons are removal of finer soil particles, erosion of upper horizons, paucity of soil plasma, the degree and intensity of factors of soil formation etc. [43,[45][46][47][48] (Harshitha et al 2018). The color of soils in high altitude varied from dark brown to brown and in mid altitude it varies from dark brown to pale yellow.…”

The scientific study of the soil started almost 70-80 years ago with two school of thoughts, one worked in the lab and others in field. The main aim of the researchers studying in the field was to determine the profiles of soil along with its horizons so as to extent the knowledge on physical, chemical and biological properties. The distinctness of soil with depth means that soil has unique profile. All the soils in the world has some specific depth functions. The change of soil color or soil texture in a soil profile can be considered a good indicator of the soil formation and process and has been used as a proxy for degree of development or soil age. Uniform, gradational and rapidly changing soil textures are examples of soil profile forms used for soil classification. In the current study we studied twelve profiles having four different land uses and observed several horizons having various boundaries. The upper horizons were having diffused and wavy boundaries than the lower horizons. There was seen a clear relationship between the horizons and the various land uses. The study is very important as the soils in Himalayas are not very well developed and are prone to erosion. The study will help researchers and policy makers.

“…Interestingly, Embu had the highest initial SOM content of all four sites, and may therefore be classified as high fertility soil, unresponsive to mineral N addition (Vanlauwe et al, 2015;Kihara et al, 2016). On the other hand, the fact that Embu was responsive to organic resource treatments may be related to better soil structure and its positive effects on the soil water balance (Bashir et al, 2021), and thus not only to the N supply from the organic resources. The non-responsiveness to mineral N in Embu is possibly because other factors than N are limiting crop growth.…”

“…Soil management practices such as addition of organic fertilizer can increase TN up to 0.25% [28] [29]. Organic matter affects physical, chemical, and biological properties such as soil pH, CEC, base saturation, and exchangeable cations, so the increasing organic matter in the soil can impact the soil [30].…”

Trees and soil management practices (i.e., pruning and fertilization) are essential in maintaining the soil fertility and coffee yield sustainability in coffee agroforestry systems. This study aimed to evaluate the impact of trees and soil management practices on the soil nutrient status within coffee-based agroforestry systems. The research was conducted in coffee agroforestry systems within Universitas Brawijaya Forest (UB Forest) from January to July 2023. The experiment was performed using a factorial randomized block design with three factors, including: 1) pruning of coffee (T1: pruned coffee, T2: unpruned coffee), 2) Fertilizer type (O: organic fertilizer, A: inorganic fertilizer, M:50% organic + 50% inorganic), and 3) Fertilizer dosage (D1: Farmer‘s dose, D2: recommended doses from the Indonesian Coffee and Cacao Research Institute (ICCRI), D3: Dosage from nutrient replacement), totaling 18 treatments with four replications of each. The soil sample was collected at topsoil (20 cm soil depth) around 50 cm from the coffee stem at the beginning of the research and six months after fertilization. The study revealed that tree management affected (p>0.05) soil nutrient status (i.e., soil total N and available P), where pruned coffee management increased soil nutrient status by 2.02 to 4.53 times compared to the unpruned coffee plot. Types and doses of fertilizer significantly affected soil pH (P < 0.05), where the application of organic fertilizer with the recommended dose (OD2) had the highest soil pH. The correlation analysis showed that soil nutrients correlated to coffee yield. The principal component analysis shows that pruned coffee combined with mixed fertilizer at the farmer‘s dose (T1MD1) is closely related to coffee production.
