“…According to the relative resorption hypothesis, when plants are P‐limited, they are inclined to resorb proportionately more P from senescing leaves, compared to N (PRE > NRE) or K (PRE > KRE), and thus there remains proportionately less P than N or K in the senesced leaves, and a higher N:P or K:P in senesced leaves than in green leaves (Han et al, ). Furthermore, owing to the drought‐induced slow litter decomposition, desert environments afford plants less chance to recover nutrients from abscised litter (Drenovsky et al, ; Ganeshamurthy & Reddy, ). The large variation in PRE (CV = 30%) may reflect the higher sensibility of plant P to the low P availability in desert soils, compared with the variations in NRE and KRE (the CV is 27% and 29%, respectively).…”

Plant nutrient stoichiometry and resorption efficiency are important functional traits related to plant nutrient status and biogeochemical cycling. Such traits are not well documented for desert shrubs. We studied how the stoichiometry and resorption efficiency of nitrogen (N), phosphorus (P) and potassium (K) varied among nine dominant desert shrub species through systematically investigating their concentrations in green and senesced leaves (or assimilation branches) of desert plants at 24 sites across Xinjiang, China. We hypothesized that desert shrubs should have low leaf N and P but high leaf K concentrations; and have high leaf N and P but low K resorption efficiency, given the low N and P but high K availability in this arid region. These shrubs had a mean leaf N concentration of 18.9 mg g−1, and lower leaf P but higher leaf K concentration (1.2 and 17.0 mg g−1, respectively) than desert plants at national and global levels. The mean (± SE) resorption efficiencies of leaf N, P and K in the desert shrubs were 51.0 ± 2.4%, 54.9 ± 2.0% and 46.3 ± 3.5%, respectively, lower than in the woody plants globally. The higher green‐leaf N:P (17.2 ± 0.8) and K:P (15.3 ± 1.0) relative to the corresponding critical ratios, and the higher P resorption efficiency (54.9%) relative to N (51.0%) and K (46.3%) resorption efficiency, suggested that the dominant desert shrubs in Xinjiang generally suffer from P (or both P and N) deficiency. Additionally, our results showed little evidence of higher resorption relative to their counterparts in most other ecosystems.

“…Their extended physiological stages of growth, differential root distribution pattern, growth stages from the point of view of nutrient requirement and preferential requirement of some nutrients like calcium, boron etc., collectively make it nutritionally more efficient than any annual crops. Mango has the ability for colonization in low fertility soils and dry-land areas by virtue of long leaf life span, leaf nutrient resorption efficiency, nutrient use efficiency and nutrient proficiency (Ganeshamurthy and Reddy 2015). Mango is cultivated on all soil types like alluvial soils, red soils, laterite soils, black soils and both in hills and plains and plateau regions and on both shallow and deep rooted soils.…”

Mango the “King of fruits” is the most important fruit crop in India and the area under mango is the largest among fruit crops (2,516 thousand ha) with a production of around 19.69 million tonnes. India ranks first in mango production in the world contributing 41% of the total world production of mango. Among Indian states, with a total output of 4.3 million MT, Uttar Pradesh stands first as mango producing state. (Fig.1).This is followed by Telangana (2.73 million MT), Karnataka (1.75 million MT) and Bihar (1.36 million MT). Particularly in India all stages of mango fruit are used starting from immature to over ripe stages. Mango has specific problem of alternate bearing leading many times to low yields or no yield.

“…It is a tropical tree species, with a broad canopy and evergreen leaves, that can tolerate long dry periods and low-nutrient soils, and also has efficient nutrient absorption (Ganeshamurthy and Reddy, 2015). Additionally, mango trees produce fruit that is a source of nutrients, vitamins and dietary fiber (Kumar et al, 2015).…”

“…Additionally, mango trees produce fruit that is a source of nutrients, vitamins and dietary fiber (Kumar et al, 2015). In this scenario, mango trees may be used to provide ecosystem services for trapping (soil quality and food production), and regulation (climatic regulation) (Ganeshamurthy and Reddy, 2015;Kumar et al, 2015). In Brazil, the mango is the 7 th most-produced fruit, and in 2015 the country produced 976,815 t of mango and harvested 64,305 ha, with yield of 15.19 t ha -1 (IBGE, 2015).…”

This graph shows the influence of rainfall on the seasonal variation in cadmium (Cd) concentration in water samples from five reservoirs (R) and an artesian well (home). Intensive farming using agrochemicals (fertilizers and pesticides) can increase heavy metal concentrations in the soil-water-plant system, especially in the case of elements poorly retained by the soil and easily lost to leaching.

Heavy metals in waters used ABSTRACTThe consumption of contaminated water is a major source of heavy metal contamination in humans and animals. This study therefore aimed to assess Cd, Cu, Mn, Ni, Pb, and Zn levels in water used for human and animal consumption and vegetable crop irrigation in Camocim de São Félix, Pernambuco, Brazil. Water samples were collected on the studied farms from an artesian well and reservoirs used for human and animal consumption as well as for crop irrigation. The results showed that concentrations of Cd (> 0.001 mg L -1 ), Ni (> 0.025 mg L -1 ) and Pb (> 0.01 mg L -1 ) were above the maximum allowable limits established under Brazilian law, indicating the need for a preventive monitoring program and immediate intervention initiatives aimed at the sources of contamination. The results demonstrate the need to quantify heavy metal content in vegetable crops, since their contamination by irrigation water may make them harmful to human health. Rainfall has a seasonal effect on heavy metal concentrations in water, showing a significant effect on Pb levels, whereas Cd and Ni content was less dependent on seasonal variation. e na irrigação de hortaliças no município de Camocim de São Félix (PE). Nas propriedades agrícolas, as amostras de água analisadas foram coletadas de poço artesiano e de reservatórios destinados ao consumo humano, animal e irrigação das lavouras. Os resultados demonstraram que as águas analisadas no presente estudo apresentaram concentrações de Cd (> 0,001 mg L -1 ), Ni (> 0,025 mg L -1 ) e Pb (> 0,01 mg L -1 ) superiores aos teores máximos permitidos indicados pela legislação brasileira, sinalizando a necessidade de um programa de monitoramento preventivo e ações de intervenção imediata das fontes de contaminação. Os resultados indicam a necessidade de quantificação das concentrações de metais pesados nas hortaliças, visto que contaminadas pelas águas de irrigação podem ser uma fonte nociva à saúde humana. A precipitação pluviométrica tem influência sobre a variação sazonal dos teores dos metais nas águas, com maior efeito na concentração de Pb e influência moderada nas concentrações de Cd e Ni.Palavras-chave: agroquímicos, cádmio, chumbo, elementos-traço, poluição difusa.
