Abstract
Animal manures may be a sustainable alternative to rock phosphate-based fertilisers, provided they have similar agronomic phosphorus (P) fertiliser values. If higher application rates from manure are required to match crop yield responses to mineral P fertilisers, soil P can accumulate and P use efficiency of the farming system is reduced. This study investigated the P fertiliser value of various manures compared to monoammonium phosphate (MAP). A P dose-response experiment assessed the impact of cattle (CaM), chicken (ChM), and pig (PiM) manures compared to MAP on wheat growth (biomass, grain yield) and P uptake in an Arenosol. The effects of subsurface banding versus incorporation were also evaluated in an Arenosol and a Ferralsol, with post-harvest soil P fractions analysed in selected treatments. To achieve 95 % maximum grain yield, P rates required were in order PiM > CaM = MAP > ChM. The ChM treatment had poor growth at high manure application rates due to sodium toxicity. Mixed through the topsoil, CaM and PiM increased biomass (95 % of maximum) by 12.3 % and 9.9 % and grain yield (95 % of maximum) by 19.7 and 20.9 % relative to banded MAP. Subsurface banding enhanced P uptake in a high P-sorbing Ferralsol, while incorporation enhanced uptake in a low P-sorbing Arenosol. In the Ferralsol, more P was retained in the sodium bicarbonate extractable organic P (NaHCO₃-Po) fraction with CaM and in the inorganic P (NaHCO₃-Pi) fraction with MAP. Cattle manure and PiM had comparable or greater P fertiliser value than MAP for wheat yields, with the application method likely impacting P availability. These findings demonstrate that certain manures can match or exceed the agronomic P fertiliser value of MAP in wheat production.
期刊介绍:
Agriculture, Ecosystems and Environment publishes scientific articles dealing with the interface between agroecosystems and the natural environment, specifically how agriculture influences the environment and how changes in that environment impact agroecosystems. Preference is given to papers from experimental and observational research at the field, system or landscape level, from studies that enhance our understanding of processes using data-based biophysical modelling, and papers that bridge scientific disciplines and integrate knowledge. All papers should be placed in an international or wide comparative context.
