“…Impact of all land uses on micronutrients content revealed significantly greater levels in forest land use in comparison to all other land uses and that might be due to the increased intensity of OM in forest soils developed through higher litter fall and root biomass that elevated the aeration status of soils, prevent oxidation and precipitation of micro-nutrients in bound forms along with supplementation of chelating agents that enhanced solubility and availability of micronutrients in soils [ 53 , 54 ]. Our results are in line with outcomes of some workers [ 47 , 53 , 55 ].…”

“…This showed that, 9200–9300 g Zn ha −1 remained unutilized; while increase in soil DTPA-extractable Zn content was 3100–3700 g ha −1 (42–54% of the total Zn applied in one cycle of RWCS). The remaining quantities either get fixed in the form which is not extracted by DTPA or form chemical compounds with other elements observed in soil 60 .…”

Nutrient uptake by the rice–wheat cropping system (RWCS) is an important indicator of soil fertility and plant nutrient status. The hypothesis of this investigation was that the rate and sources of nutrient application can differentially influence nutrient removal and soil nutrient status in different crop establishment techniques (CETs). Cropping system yield was on par in all the CETs evaluated, however, there were significant changes in soil nutrient availability and microbiological aspects. The system nitrogen (N), phosphorus (P), potassium (K) and zinc (Zn) uptake in aerobic rice system followed by zero tillage wheat (ARS-ZTW) was 15.7–17.6 kg ha−1, 0.7–0.9 kg ha−1, 7–9.8 kg ha−1 and 13.5–23.1 g ha−1 and higher than other CETs. The formulations of Anabaena sp. (CR1) + Providencia sp. (PR3) consortium (MC1) and Anabaena–Pseudomonas biofilm (MC2) recorded significantly higher values of soil chlorophyll and microbial biomass carbon and positively affected cropping system nutrient uptake and soil nutrient balance, illustrating the beneficial effect of microbial inoculation through increased supply of biologically fixed N and solubilised P. Zinc fertilization (5 kg Zn ha−1 through ZnSO4·7H2O as soil application) increased soil DTPA-extractable Zn by 4.025–4.836 g ha–1, with enhancement to the tune of 20–24% after two cropping cycles of RWCS. Our investigation recommends the need for change in the present CETs to ARS–ZTW, along with the use of microbial inoculation as a means of significantly enhancing cropping system nutrient uptake and soil nutrient status improvement.

“…Distribution of DTPA-Zn under variable soil orders followed the trend of Entisol > Inceptisol > Aridisol. The greater contents under Entisol and Inceptisol correspond to the addition and recycling of Zn through the accumulation and decomposition of organic residues added to the soil in the form of litter and root residues, leading to increased microbial activity in the soil and thereby facilitating the release of micronutrients in the soils [42,46]. The lower Zn content under Aridisol might be due to exhaustive cultivation leading to continuous crop removal and nutrient decline in the soil [47].…”

“…The peak content of DTPA-Fe among different soil orders was under Entisols, and that corresponds to an increase in the availability of organic Fe fractions of Fe in these soils comprising of greater OM content. The greater Fe content might also be due to the greater addition of organic residues that enhanced soil aeration, supplied chelating agents and prevented the precipitation and oxidation of Fe, thus increasing the availability of micronutrients in soils [46,47]. The variation may also relate to other aspects such as the variations in Fe containing minerals or the extraction efficiency of variable chemical extractants.…”

The agricultural production in Punjab has increased manifold that aggravated the deficiencies of micronutrients in soils and plants. The availability of soil micronutrients in different soil orders depends upon the soil mineralogy, topography, climatic conditions and cropping sequences. Hence, to study the pedospheric variations of DTPA-extractable micronutrients, viz., zinc (Zn), iron (Fe), manganese (Mn) and copper (Cu), in three prominent soil orders of Punjab, a total of 144 depth-wise soil samples were collected from four major land-use systems (cultivated, horticulture, forest and pasture lands). The DTPA extractable micronutrients varied from 1.74–2.81, 1.83–2.82 and 1.81–2.80 for Zn; 5.3–6.8, 5.6–6.9, 4.3–6.3 for Fe; 5.1–7.8, 5.5–7.9, 5.4–7.5 for Mn; and 0.84–1.40, 0.93–1.68, 0.87–1.65 for Cu in soil orders Aridisol, Entisol and Inceptisol, respectively. The average content of DTPA-extractable micronutrients was highest under soil order Entisol followed by Inceptisol and Aridisol. The content of micronutrients showed a declining trend with increase in soil depth in all orders. Among different soil properties, the pH and EC showed significantly negative correlation, however, OC had non-significant correlation with DTPA-extractable micronutrients in soils. Therefore, it is concluded that parent material, land use systems and soil depth affected the distribution of DTPA extractable micronutrients in different soil orders.
