“…First, green manure enhances the effectiveness of nitrogen uptake while reducing nitrogen leaching loses [ 27 ]. For instance Sanaullah et al [ 70 ] reported that green manure plants have the potential to fulfill 40–60 % of the total nitrogen requirement of subsequent crops. Additionally, they improve soil fertility by promoting nutrient retention, increasing soil organic matter (SOM), and enhancing microbial biomass [ 71 ].…”

“…Deep placement, injection, and side dress are more efficient than broadcasting (Fageria and Baligar, 2005;De Laporte et al, 2021;Sanaullah et al, 2022). Deep placement is more efficient than broadcasting, with 62% more N uptake and; a reduction in leaching, immobilization, and volatilization observed (Raun and Johnson, 1999;Flis, 2017;Sanaullah et al, 2022). Nitrogen application through foliar and fertigation are better than broadcasting and increase NUE, and fertigation can also improve water use efficiency (Raun and Johnson, 1999;Demir et al, 2021).…”

Nitrogen (N) is an essential and limiting nutrient for crop production, as it is a structural part of plants and is involved in various processes. Worldwide, agricultural soils lack one or more essential nutrients, and nitrogen is one of them. Adding a sufficient amount of N will increase production. However, the overuse of N and loss of N from the soil-plant system are detrimental to the environment and result in economic losses. Nitrogen has reactive forms like ammonia, ammonium, nitrate, nitrite, nitric oxide, and nitrous oxide. Some reactive forms of N are harmful to humans, animals, plants, and microbial ecology. Nitrate can cause the eutrophication of surface water and contamination of groundwater. Drinking nitrate contaminated water can cause methemoglobinemia and other health issues. Nitrous oxide emission depletes the ozone layer and contributes to climate change. Ammonia emissions contribute to acid rain and are also responsible for nitrous oxide emissions. This review addresses different factors/pathways/circumstances that contribute to the loss of N from the soil-plant system and reduce nitrogen use efficiency (NUE). Different factors influence NUE like ammonia volatilization, nitrification, denitrification, immobilization, leaching, runoff, temperature, soil pH, soil texture, rainfall & irrigation, soil salinity, tillage, weeds, pests, diseases, N loss from plants, fires, crop rotation, crop nutrition, crop varieties, and nitrogen management (right time, right source, right place, and right rate/amount).

“…Hence, it is readily lost, especially from the calcareous soils such as those of Pakistan 53,54 . This loss not only affects the quality of the soil but it also translates into economic loss in terms of annual crop production [55][56][57] . Nitrogen use efficiency within the Pakistani agriculture system rarely go beyond 40%.…”

Global warming is a wide-scale problem and soil carbon sequestration is its local scale, natural solution. Role of soil as carbon sink has been researched extensively but the knowledge regarding the role of soil variables in predicting soil carbon uptake and its retention is scarce. The current study predicts SOC stocks in the topsoil of Islamabad-Rawalpindi region keeping the soil properties as explanatory variables and applying the partial least square regression model on two different seasons’ datasets. Samples collected from the twin cities of Islamabad and Rawalpindi were tested for soil color, texture, moisture-content, SOM, bulk density, soil pH, EC, SOC, sulphates, nitrates, phosphates, fluorides, calcium, magnesium, sodium, potassium, and heavy metals (nickel, chromium, cadmium, copper and manganese) by applying standard protocols. Afterwards, PLSR was applied to predict the SOC-stocks. Although, current SOC stocks, ranged from 2.4 to 42.5 Mg/hectare, but the outcomes of PLSR projected that if soil variables remain unaltered, the SOC stocks would be likely to get concentrated around 10 Mg/hectare in the region. The study also identified variable importance for both seasons’ datasets so that noisy variables in the datasets could be ruled out in future researches and precise and accurate estimations could be made.
