Soil organic carbon content and stock in Martinique – relations to near infrared spectra Open
This data paper presents observations on soil organic carbon (SOC) gravimetric and volumetric contents (SOCg, in g kg −1 , and SOCv, in g dm −3 , respectively) for 98 profiles at least 30 cm deep (1 m deep for 59 of them), in rural areas o…

Comparison of soil organic carbon stocks predicted using visible and near infrared reflectance (VNIR) spectra acquired in situ vs. on sieved dried samples: Synthesis of different studies Open
There is increasing demand for data on soil organic carbon (SOC) stock (SSOC; kgC m−2), but the acquisition of such data, which relies on the determination of volumetric SOC content (SOCv; gC dm−3), is often tedious or complex. Visible and…

Concurrent starch accumulation in stump and high fruit production in coffee (<i>Coffea arabica</i>) Open
In coffee, fruit production on a given shoot drops after some years of high yield, triggering pruning to induce resprouting. The timing of pruning is a crucial farmer’s decision affecting yield and labour. One reason for fruit production d…

Using absorbance peak of carbonate to select suitable regression model before predicting soil inorganic carbon concentration by mid-infrared reflectance spectroscopy Open
<p><span>Mid-Infrared reflectance spectroscopy (MIRS, 4000 &#8211; 400 cm<sup>-1</sup>) is being considered to provide accurate estimations of soil inorganic carbon (SIC) contents. Usually, the prediction perfor…

Infrared spectroscopy approaches support soil organic carbon estimations to evaluate land degradation Open
Soil organic carbon (SOC) is an acknowledged indicator for land degradation, but conventional determination of SOC remains tedious, especially regarding SOC stock (in kg C m −2 for a given depth layer), which is the product of SOC concentr…

K competition between crops and young oil palm in agroforestry systems in the Allada plateau smallholdings, Benin Open
Beninese smallholders associate food or cash crops with young oil palm stands to reduce field maintenance costs and gain income before the oil palm comes into production. However, little is known about the effects of these agroforestry sys…

Ramial wood amendments (<span><i>Piliostigma reticulatum</i></span>) mitigate degradation of tropical soils but do not replenish nutrient exports Open
Restoring degraded soils to support food production is a major challenge for West African smallholders who have developed local innovations to counter further degradation. The objective of this study was to evaluate a local farmer's techni…

Predicting and Mapping Topsoil Black Carbon of France Open
Black Carbon (BC) in soil is considered a stable or resistant form of carbon, and thus itis important to determine its amount relative to the Total C (TC). As measurement of BC isquite time-consuming, involving chemo-thermo-oxidation at 37…

A global spectral library to characterize the world's soil Open
Soil provides ecosystem services, supports human health and habitation, stores carbon and regulates emissions of greenhouse gases. Unprecedented pressures on soil from degradation and urbanization are threatening agro-ecological balances a…

Agroforestry for a climate-smart agriculture – a case study in France Open
Agroforestry is a land use type where crops and trees are grown together in the same place and at the same time. Agroforestry systems have the advantage of providing multiple products (e.g. wood, fruits) or services (e.g. biodiversity enha…

Can woody plants management provide soil amendments to enhance agroecosystem productivity and resilience in West Africa? [P66] Open
Soil degradation and fertility loss pose severe threats to the livelihood of farmers in sub-Saharan regions. Due to the need for land, continuous cultivation with staple food has gradually replaced previous shifting cultivation systems, so…
