“…For black pepper, the application of fertiliser needs to also consider the slope of the area. This consideration is particularly attributed to the nutrient transportation and accumulation whereas N found greater in middle and slope position, P in footslope and K in upper slope (Uzoho et al, 2016;Samndi and Mahmud, 2014). One of the ways to increase fertiliser efficiency and reduce soil pollution derived from fertiliser application for pepper planted at the steep area is growing a barrier crop nearby the surface water (Yulnafatmawita et al, 2017;Tuan et al, 2014).…”

Cultivating black pepper in Malaysia started in early 10th to the 11th century when the South Indian Kings began to extend their empire. The crop was brought to East Malaysia in 1840 by Chinese settlers, actively planted until it was hit by the massive flood, fluctuation of the price and outbreak of foot rot. High yielding cultivars such as Kuching, Semenggok Emas and Semenggok Aman provided promise for better production, but resulted in increased soil degradation and reduced crop growth in Sarawak. The paper aims to discuss the black pepper industry in Sarawak and present scenario of its cultivation including future prospects. Cultivating on hilly topography with coarse textured dominant soil becomes one of the limiting factors. This factor is observed due to high rainfall intensity and steeper slopes. Neglected soil conservation also affects crop production and lead to a lower return on investments. Technologies such as land conservation and practising precision agriculture need to be adopted to reduce the impact of soil degradation and better production.

“…K forms in most soils. Samndi and Tijjani (2014), have attributed the distribution of various forms of K along a toposequence to the degree of leaching tendency across slopes. The major factor in this result affecting the distribution of K in the result may also be the higher leaching tendency of soil under prolonged irrigation.…”

This study was carried out at Kano River Irrigation Project (KRIP) (latitudes 11º 36ʹ 0.05ʺ N to 11º 49ʹ 57.97ʺ N and longitudes 8º 28ʹ 17.02ʺ E to 8º 29ʹ 41.82ʺ E) and Hadejia Valley Irrigation Project (HVIP) (latitudes 12º 17ʹ 48.75ʺ N to 12º 24ʹ 58.28ʺ N and longitudes 9º 51ʹ 31.29ʺ E to 10º 2ʹ17.42ʺ E). The soils are largely deep, well-drained Calcic Luvisols. The aim was to assess the geospatial distribution of some plant-nutrition related forms of P and K. A total of 37 and 19 irrigation sectors were identified in KRIP and HVIP respectively. Google earth was used to tag 109 and 41 sampling points randomly within both developed and undeveloped sectors of KRIP and HVIP respectively. With the aid of projects’ sitemaps, the sectors were demarcated into six periods of irrigation: 0 years (Non -irrigated), 1-10 years, 10-19 years, 20-29 years, 30-39 years and ≥ 40 years as applicable. GPS was used to track the tagged points at the time of sampling. Sur- face soil samples were collected by augering to 30 cm depth with fabricated steel augers. Samples were analyzed for physical and chemical properties. Available (AP) and total (TP) forms of P as well as water-soluble (WSK), exchangeable (Ex. K) and non-exchangeable (NEK) forms of K were analyzed. Basic soil prop- erties were compared by ANOVA using JMP version 12. Geostatistical analysis and Geospatial variability of various forms of P and K were performed with the GS+ software (version 10). Ordinary Kriging was used for the spatial interpola- tion. Texturally, the soils of the KRIP was sandy loam while that of the HIVP was predominantly sandy clayey loam. The pH (mean = 6.68) and EC (mean = 0.21 dsm-1) values across the sites indicated that despite the years of irrigation the areas are not under immediate salinization risk. There was no specific pattern of distribution of basic cations in both the two schemes. There is an observable tendency in the distribution of the forms of P and K evaluated of their being at higher concentrations in longer-periods irrigated lands in both the scheme. The nugget to sill ratio revealed a strong spatial dependence (< 25 %) for WSK. Moderately spatial dependence (25 to 75 %) was observed for available P, total P, noN-exchangeable K and exchangeable potassium. It was concluded that there may be a stronger influence of the irrigation method on the spatial distribution of the forms of the nutrients over other factors such as parent material and weathering.

“…Next, slope orientation can affect the nutrient availability in the soil. It is reported that at least 23.60 mg/kg of P is available on tilt-up in the upper slope compared to the steeper area (Samndi & Mahmud, 2014). Several nutrient deficiency problems reported in previous literature involving N, K, and other essential elements eventually lead to lower yields (Izzah & Wan Asrina, 2019;Srinivasan et al, 2007).…”

This study was conducted to determine the effect of the rainfall pattern on cation nutrients in black pepper cultivation in a hilly topography. A field study was conducted in black pepper cultivation in a hilly topography around Bintulu, Sarawak, Malaysia, with a 26o slope during the Northeast monsoon in 2020. Six blocks were established on 462.56 m2, with four subsequent soil samples (0-20 cm) collected per block after the rainfall. Soil samples were analysed using the standard pH, total organic carbon (TOC), soil texture, total nitrogen (TN), available phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), and manganese (Mn) in triplicate. Rainfall pattern (October < November > December) affects TN (300.31-1422.90 mg/kg) and K availability (13.54-166.68 mg/kg), especially during peak season in November 2020. Available P, Ca, Mg, Fe, and Mn exhibit minimum rainfall effect but are closely related to combined interaction with parent material and topography. Therefore, proper soil management, such as applying fertiliser using top dressing, foliar spray, and manure amendment, including growing cover crop, is recommended to improve nutrient availability.
