    Published 1995
    “…The main effects of lime on groundnuts were, therefore, to supply adequate Ca to: (1) produce maximum number of mature pods and (2) diminish the incidence of unfilled pods.…”

    Published 2022
    “…No Fe problems were observed and the Mn and Zn problems found by soil analysis were not reflected in the greenhouse data Only some soils from the Cordillera de Guanacaste respond positively to Cu application. Ca concentration in 1ypic Dystrudepts of Costa Rica varies, with a 90h statistic probability.rom 32 to 1.7 meg/100 m, Ms, from 0.9 to 3 2 meal100 mi, K, from o03 to 083 meal100 ml, Fe. from 27 to 104 Hg/ml, Mn from traces to 60 H8/ml, Zn, from 14 to 70 Hg/ml and Cu, from traces to 23 4g/ml Soil pH in water varies between 5.6 and 6 7 and in KC between 4.9 and 56 Exchangeable acidity varies from 0 07 to 0 12 meq|100 ml. …”

  4. Soil quality and soil fertility status in major soil groups at the Tombel area, South-West Cameroon by Nguemezi, C., Tematio, P., Yemefack, Martin, Tsozue, D., Silatsa, T.B.F.

    Published 2020
    “…Based on physicochemical soil properties, fertility parameters and Soil Quality Index (SQI), four soil fertility classes were identified in the area: (i) very good fertility soils (66 km2) that corresponds to Dystric Vitric Andosols (Melanic) above 500m asl; (ii) good fertility soils (506 km2), grouping Dystric Vitric Andosols (Melanic) below 500m asl and Leptic Fragic Umbrisols; (iii) fairly good fertile soils (787 km2) including Dystric Fragic Cambisols (Humic), Rhodic Acrisols (Cutanic Humic), Fragic Umbrisols (Arenic), and Mollic Ferralsols (Eutric Humic); (iv) poorly fertile soils (375 km2) including Umbric Andosols (Fragic) and Umbric Pisoplinthic Plinthosols (Haplic Dystric). …”
