“…The increases in yields of wheat and maize noticed in the current study owing to the application of the organic amendments agree with findings reported by Cherif et al (2009), Alemazadeh andKazemeini (2010) and Blaser et al (2012). Rasool et al (2008), Anyanzwa et al (2010) and Chivenge et al (2011) reported significant increases in maize productivity due to application of the organic amendments. Treatments receiving the organic amendments, especially at the higher application rates showed significant higher organic carbon after cropping.…”

“…It is peculiar that residue retention combined with mineral fertilizer did not have a beneficial impact on upper soil C as found in numerous other studies (Vanlauwe et al, 2001;Bationo et al, 2007;Chivenge et al, 2007;Anyanzwa et al, 2010;Chivenge et al, 2011). A possible explanation could be the low residue cover in the present study.…”

“…Numerous field studies reported increased yields from crop residue application in addition to mineral fertilizer (Palm et al, 2001;Vanlauwe et al, 2001;Anyanzwa et al, 2010), especially under reduced tillage (Govaerts et al, 2005). In our study, the total average soybean grain yield under reduced tillage without residue retention (-T-R) was 45% lower than under the other treatments.…”

“…It is also worth noting that the N in plant components was significantly different across treatments and which if retained as crop residues could improve soil fertility, water retention, and crop yields (Anyanzwa et al, 2010; Gentile et al, 2009; Tongwane et al, 2016). Crop residue retention could also cause higher N 2 O emissions (Basche et al, 2014; Peyrard et al, 2016); however, retention of crop residues on the field is not a common practice in the study area as the maize stalks are used as animal feeds and as fuel for cooking.…”

Soil Greenhouse Gas Fluxes From Maize Production Under Different Soil Fertility Management Practices in East Africa

In sub‐Saharan Africa (SSA), few studies have quantified greenhouse gas (GHG) emissions following application of soil amendments, for development of accurate national GHG inventories. Therefore, this study quantified soil GHG emissions using static chambers for two maize cropping seasons (one full year) of four different soil amendments in the central highlands of Kenya. The four treatments were (i) animal manure, (ii) inorganic fertilizer, (iii) combined animal manure and inorganic fertilizer, and (iv) a no‐N control (no amendment) laid out in a randomized complete block design. Cumulative annual soil fluxes (February 2017 to February 2018) ranged from −1.03 ± 0.19 kg CH4‐C ha−1 yr−1 from the manure inorganic fertilizer treatment to −0.09 ± 0.03 kg CH4‐C ha−1 yr−1 from the manure treatment, 1,391 ± 74 kg CO2‐C ha−1 yr−1 from the control treatment to 3,574 ± 113 kg CO2‐C ha−1 yr−1 from the manure treatment, and 0.13 ± 0.08 to 1.22 ± 0.12 kg N2O‐N ha−1 yr−1 in the control and manure treatments, respectively. Animal manure amendment produced the highest cumulative CO2 emissions (P < 0.001), N2O emissions (P < 0.001), and maize yields (P = 0.002) but the lowest N2O yield‐scaled emission (YSE) (0.5 g N2O–N kg−1 grain yield). Manure combined with inorganic fertilizer had the highest cumulative CH4 uptake (P < 0.001) and N2O YSE (2.2 g N2O–N kg−1 grain yield). Our results indicate that while the use of animal manure may increase total GHG emissions, the concurrent increase in maize yields results in reduced yield‐scaled GHG emissions.
