“…Acacia roots may have obtained some unavailable form of nutrients by accelerating soil weathering as reported for other plants (Sugiyama & Ae 2000). The nutrients released from the unavailable fractions of mineral soils could be easily leached into the deeper layers in acidic soil conditions with low cation exchange capacity as suggested by the low pH in this study site (Mori et al 2013). It is possible that the effects of fertilisation on soil Mg contents through stimulated Mg uptakes were masked by the large decrease in soil Mg pools during the experiment.…”

“…Acacia mangium seedlings were planted at 3 m × 3 m intervals at the beginning of February 2008 as the second rotation of the plantation. TSP fertilisation had no effects on soil pH (H 2 O) during the whole period of the experiment (Mori et al 2013). …”

“…The increase in leaf biomass by TSP fertilisation was estimated using the same increment rate as aboveground biomass increment by TSP fertilisation at 9-month-old stands (171% from 2.1 to 3.6 t ha -1 , Mori et al 2013). The potential exports of K and Mg through tree harvest were calculated to ascertain the effects of TSP fertilisation.…”

“…There are no reports on effects of TSP fertilisation on stem nutrient contents in tree plantations. Stem biomass increment caused by TSP fertilisation were assumed to be the same as those of aboveground biomass in a 20-month-old stand (Mori et al 2013). We used data on stem (> 8 cm) K (59.7 kg ha -1 ) and Mg (17.6 kg ha -1 ) contents taken from a 10-year-old stand of the first rotation in another stand at our study site (Hardiyanto & Nambiar 2014).…”

Since nutrients have either synergetic or antagonistic effects, fertilisation has potential to change harvest export of other nutrients present in plantations. In the present research, we investigated the effects of triple superphosphate (TSP) fertilisation on Mg and K contents of leaf and soil pools in a monoculture Acacia mangium plantation in South Sumatra, Indonesia. TSP fertilisation reduced leaf K concentration, but leaf K content per stand area did not show any difference between control and fertilised plots because of the offset by stimulated biomass increment following fertilisation. TSP fertilisation significantly elevated both leaf Mg concentration and leaf Mg content per stand area, indicating the stimulated Mg uptakes by trees. Despite the stimulated uptakes, soil Mg pools were not affected by the fertilisation. It was possibly because the decrease in soil Mg pools during the experimental period was much greater than the stimulated Mg uptakes deriving from the fertilisation. Although the soil nutrient pools were not affected by TSP fertilisation in the present study, our results of the increased leaf Mg contents and the estimated future harvest export of Mg suggest that unbalanced fertilisation can accelerate nutrient export from plantation soils through harvesting.

A study was conducted in none tilled coffee agroforestry fields of Eastern Uganda to understand the effects of application of inorganic fertilizers on soil nutrient loss in form of gas for mitigation of unsustainable agricultural practices. This study specifically i) assessed the effect of application of inorganic fertilizers on greenhouse gas emissions, ii) determined their effect on microbial carbon, nitrogen and phosphorus and iii) determined their effect on leaf litter decomposition under Albizziacoffee growing systems of the Mount Elgon. Soil gas emissions were measured with the static chamber method for twelve months in a field experiment with five different fertilizer treatments. The effect of treatments was separated using ANOVA in Genstat discovery version 13. Microbial carbon, nitrogen and phosphorus was separated using Mann-Whitney U test. Results showed that annual emissions ranged from 19.6 to 26.1 (t C/ha/yr), 3.5 to 9 (Kg N/ha/yr) and 6.9 to 9.2 (Kg C/ha/yr) for carbon dioxide, nitrous oxide and methane respectively. Significant effects on soil emissions only occurred for nitrous oxide (P=0.017), microbial carbon (p=0.001) and microbial phosphorus (p<0.001) for the study period. The mixture of NPK fertilizers presented the lowest carbon dioxide loss and application of TSP presented the lowest nitrous oxide emission from soil. This study underscores the need for establishment of long-term experiments across several agro-ecological zones to confirm farmers' perceptions of their soil fertility levels and ascertain the contribution of farm practices towards the retention of nutrients in the soil with minimal emission, to inform decisions of small holder farmers, policy and development partners for sustainable production.
