“…In this study, applications of N plus P, and N, P plus K significantly increased rice yield (average value from the year of 2005 to 2009), while applications of N alone and N plus K had no significant effect on rice yield, indicating the importance of long-term P fertilizer application in promoting crop yield. Furthermore, balanced fertilization of N, P plus K had a higher rice yield than the other fertilization treatments (N, NP and NK), suggesting a positive impact of balanced chemical fertilizer applications on crop production, in accordance with previous reports that balanced fertilization resulted in higher crop yield (Gu et al 2009;Shang et al 2014). The PCA of basic chemical properties showed that the NP and NPK treatments were clustered together and distinct from the control, N and NK treatments on PC1, this further confirmed that P availability is a key factor for nutrient cycling and fertility in this soil.…”

The influence of long-term chemical fertilization on soil microbial communities has been one of the frontier topics of agricultural and environmental sciences and is critical for linking soil microbial flora with soil functions. In this study, 16S rRNA gene pyrosequencing and a functional gene array, GEOCHIP 4.0, were used to investigate the shifts in microbial composition and functional gene structure in paddy soils with different fertilization treatments over a 22-year period. These included a control without fertilizers; chemical nitrogen fertilizer (N); N and phosphate (NP); N and potassium (NK); and N, P and K (NPK). Based on 16S rRNA gene data, both species evenness and key genera were affected by P fertilization. Functional gene array-based analysis revealed that long-term fertilization significantly changed the overall microbial functional structures. Chemical fertilization significantly increased the diversity and abundance of most genes involved in C, N, P and S cycling, especially for the treatments NK and NPK. Significant correlations were found among functional gene structure and abundance, related soil enzymatic activities and rice yield, suggesting that a fertilizerinduced shift in the microbial community may accelerate the nutrient turnover in soil, which in turn influenced rice growth. The effect of N fertilization on soil microbial functional genes was mitigated by the addition of P fertilizer in this P-limited paddy soil, suggesting that balanced chemical fertilization is beneficial to the soil microbial community and its functions.

“…Similarly, compared to NP straw return did not have any significant impact on yields of either wheat or maize from 1982 to 2003 at a long-term experimental site (LTE) on the North China Plain (Zhao et al, 2009). Data from LTEs in China show that the mean yields were similar between NPK and NPKS for maize and wheat crops but NPKM or NPKS had the lowest variability in cereal productivity compared to unbalanced fertilization treatments including NK, PK or a control (Shang et al, 2014). Therefore, it is likely that straw amendment in combination with compost can be a good management approach to increase maize yields and decrease the variability in the long term.…”

Abstract. In order to investigate the soil fertility status of Swabi district the present research was carried out. A total of 32 soil samples were collected from 16 different locations surrounding Swabi area at 0-20cm and 20-40cm depths and analysed for different chemical properties and fertility status in the laboratory of soil and environmental Sciences University of Agriculture Peshawar. Results revealed that soil of Swabi was moderately to strongly calcareous in nature and alkaline in reaction. The O.M content was found deficient to marginal, being deficient in 75% and marginal in 25% samples at both soil depths. AB-DTPA Extractable phosphorous was found sufficient (40%) at surface soil while at sub surface it was found 15% deficient. No potassium deficiency was observed at surface as well as at sub surface soil, being sufficient in 37 % samples at surface soil and 43 % samples at sub surface soil. AB-DTPA extractable Cu was found adequate in almost all soil samples, Fe was found sufficient in 78% soil samples and medium in 9% samples and was found low in 12% soil samples at both soil depths. AB-DTPA Extractable Zn was found 12% deficient, 6% medium and 31% adequate at all surface soil samples while at sub surface it was found 19% deficient, 22% medium and 12% adequate. Proper fertilization and application of FYM and green manure is highly recommended for the areas low in Organic matter and respective nutrients.
