  1. Soil fertility under native cerrado and pasture in the Brazilian savanna by Lilienfein, J, Wilcke, W., Vilela, Lourival, Ayarza, Miguel Angel, Carmo Lima, S. do, Zech, W.

    Published 2003
    “…To evaluate biophysical pasture sustainability we compared regularly fertilized productive pasture (PP), degraded pasture fertilized 13 yr previously (DP), and native savanna (Cerrado, CE) in an on-farm experiment. We determined (i) biomass productivity of the pastures and (ii) nutrient concentrations in Anionic Acrustoxes from three plots under each of CE, DP, and PP. …”

  3. Distribution of water-stable aggregates and aggregating agents in oxisols of the Brazilian cerrados by Neufeldt, Henry, Ayarza, Miguel Angel, Resck, DVS, Zech, W.

    Published 1999
    “…The effects of land-use change on the structure of Oxisols in the Brazilian savannas (also known as the Cerrados) are still insufficiently understood. We therefore studied loamy and clayey Oxisols under natural savanna, crop, pasture, and reforestation to (1) quantify management-induced changes in the quantity of water-stable aggregates, (2) identify the main aggregating agents, and (3) correlate aggregation with changes in pore-size distribution. …”

  4. Adsorcao de nitrato em Latossolos sob vegetacao de cerrado by Velloso, Ary Carlos Xavier

    Published 2025
    “…Adsorption of nitrate by nine oxisols collected in cerrados (savannah) from Brazil was measured in solutions containing graded amounts of KNO, Nitvate adsorp-tion for B-horizons varied from 0.11 mmol/100 g for soil suspensions of pH values ranging from 4.4 to 5.0. …”

  5. Cover crop and nitrogen effects on maize productivity in no-tillage systems of the Brazilian cerrados by Maltas, A, Corbeels, Marc, Scopel, E., Wery, Jacques, Silva, F.A.M. da

    Published 2009
    “…Cover crops in direct seeding mulch‐based cropping (DMC) systems can be an effective tool to optimize N management for crop production in the Brazilian cerrados. The objective of this study was to determine the effect of four cover crops on maize (Zea mays L.) grain yields in two fields that had been under DMC for 3 and 14 yr. …”

  6. Cover crops optimize soil fertility and soybean productivity in the Cerrado of MATOPIBA, Brazil by Andrada, Hosana Aguiar Freitas de, Sagrilo, Edvaldo, Oliveira Júnior, José Oscar Lustosa de, de Sousa, Daiane Conceicao, Costa, Carlos Pedro de Menezes, Costa, Paula Muñiz, Araujo Neto, Raimundo Bezerra de, Alcantara, Rosa María Cardozo Mota de, Leite, Luis Fernando Carvalho, Furtado, Mariléia Barros, Beltran, Marcelo Javier, Cafaro La Menza, Nicolás, Souza, Henrique Antunes de

    Published 2025
    “…This study aimed to evaluate the use of cover crops (CC) to improve soil fertility, plant nutrition, and soybeans productivity grown in the Cerrado of Brazil. The study was carried out on a farm located in the state of Maranhão, Brazil, with nine treatments, fallow and CC preceding soybean cultivation: (i) Millet (Pennisetum glaucum L.); (ii) Marandu (Urochloa brizantha); (iii) Ruziziensis (Urochloa ruziziensi); (iv) Tanzania (Megathyrsus maximum); (v) Massai (Megathyrsus maximum); (vi) cowpea (Vigna unguiculata L.); (vii) pigeon pea (Cajanus cajan L.); and (viii) Crotalaria (Crotalaria juncea). …”
