1In Brazilian soil fertility management, the base saturation method is widely used to calculate the liming requirement (Necessidade de Calagem - NC). A soil analysis shows an initial base saturation (V1) of 40%, a total cation exchange capacity (CTC at pH 7.0 / T) of 10.0 cmolc/dm³, a target base saturation (V2) of 70% for soybean cultivation, and limestone with a Relative Total Neutralizing Power (PRNT) of 80%. What is the recommended liming rate in metric tons per hectare (t/ha)?
2When managing highly weathered Cerrado Oxisols (Latossolos) with low cation exchange capacity and high exchangeable aluminum, agronomists often compare the base saturation method with the aluminum neutralization method for liming. Under which soil chemical condition is the aluminum neutralization method specifically prioritized?
3Agricultural phosphogypsum (gesso agrícola - CaSO4.2H2O) is an essential subsoil conditioner in tropical agriculture. Which set of chemical criteria in the 20-40 cm or 40-60 cm soil layer indicates a technical recommendation for phosphogypsum application (gessagem) in grain cropping systems?
4A routine soil fertility analysis from a Cerrado field reports the following values: Ca²⁺ = 2.4 cmolc/dm³, Mg²⁺ = 0.8 cmolc/dm³, K⁺ = 0.3 cmolc/dm³, Al³⁺ = 0.5 cmolc/dm³, and (H + Al) = 3.5 cmolc/dm³. What are the Effective Cation Exchange Capacity (t), Total Cation Exchange Capacity at pH 7.0 (T), and Aluminum Saturation (m%) of this soil?
5Soil water retention and availability are governed by soil matric potential. What matric potential values are standardly defined in agronomy for Field Capacity (Capacidade de Campo - CC) in tropical soils and Permanent Wilting Point (Ponto de Murcha Permanente - PMP)?
6An agronomist calculates the Available Water Capacity (Capacidade de Água Disponível - CAD) for an irrigation project in a clayey Latosol. Soil analysis shows: volumetric moisture at field capacity (θCC) = 0.35 cm³/cm³, volumetric moisture at permanent wilting point (θPMP) = 0.20 cm³/cm³, and an effective crop root depth (Z) of 400 mm. What is the total CAD of this soil layer?
7Tropical Oxisols (Latossolos) typically exhibit variable (pH-dependent) charge dominated by kaolinite, gibbsite, goethite, and hematite. What happens to the net surface charge and Cation Exchange Capacity (CEC) of these soils when soil pH is raised from 4.8 to 6.2 through liming?
8The Universal Soil Loss Equation (USLE / EUPS) predicts average annual soil loss: A = R * K * L * S * C * P. Which conservation practice directly modifies the 'P' (support practice) factor to minimize water erosion in agricultural watersheds?
9The Brazilian No-Till System (Sistema Plantio Direto - SPD) is recognized globally as a sustainable soil management model. What are the three non-negotiable agronomic pillars required to maintain a genuine, certified No-Till System?
10Biological Nitrogen Fixation (FBN) in soybean (*Glycine max*) relies on symbiosis with *Bradyrhizobium japonicum* or *Bradyrhizobium elkanii*. Which micronutrients are biochemically indispensable as cofactors for the nitrogenase enzyme complex and leghemoglobin synthesis?
About the ENADE Agronomia Exam
The Exame Nacional de Desempenho dos Estudantes (ENADE) for Agronomy / Agronomic Engineering (Bacharelado em Agronomia / Engenharia Agronômica) is the premier national capstone evaluation conducted by the Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (INEP) under the Brazilian Ministry of Education (MEC). Established pursuant to Federal Law nº 10.861/2004 as part of the Sistema Nacional de Avaliação da Educação Superior (SINAES), ENADE evaluates graduating undergraduate seniors (concluintes) across Brazil. The assessment rigorously tests the student's mastery of the scientific foundations, engineering calculations, technological applications, environmental sustainability frameworks, and ethical responsibilities defined in the National Curriculum Guidelines (Diretrizes Curriculares Nacionais - DCNs) and the Federal Council of Engineering and Agronomy (CONFEA) under Federal Law nº 5.194/1966. The 2026 bachelor examination format features 46 questions: 15 General Training (Formação Geral) multiple-choice items addressing ethics, citizenship, human rights, and socio-economic dynamics, 30 Specific Component (Componente Específico) multiple-choice questions, and 1 specialized discursive problem. Topics span Soil Science & Plant Nutrition, Crop Production & Physiology, Plant Protection & Phytosanitary Management, Agricultural Engineering & Mechanization, Sustainable Livestock & Pastures, and Agribusiness Farm Economics & Environmental Law. Satisfactory completion of the exam and the mandatory Student Questionnaire is an indispensable legal prerequisite for degree conferral, professional registration with the Regional Council of Engineering and Agronomy (CREA), and the calculation of university quality indicators.

Frequently Asked Questions
What is the official structure and duration of ENADE Agronomia for the 2026 cycle?
The official 2026 bachelor examination is administered in a single 4-hour session consisting of 46 questions: 15 General Training (Formação Geral) multiple-choice items, 30 Specific Component (Componente Específico) multiple-choice items, and 1 specific discursive problem requiring applied agronomic calculation or design.
Is participation in ENADE Agronomia mandatory for undergraduate graduation?
Yes. Under Brazilian Federal Law nº 10.861/2004 (SINAES), ENADE is a mandatory curricular component for all enrolled graduating seniors (concluintes) in Bachelor of Agronomy / Agronomic Engineering programs. Completion of the exam and the mandatory online Student Questionnaire is legally required to obtain the degree diploma and register with the Regional Council of Engineering and Agronomy (CREA).
How is the Conceito Enade score calculated and used by MEC/INEP?
The Conceito Enade is calculated on a standardized 1 to 5 scale by INEP, evaluating the relative academic performance of graduating cohorts. A score of 3 indicates satisfactory compliance with national educational standards, while scores of 4 and 5 indicate high academic excellence. It serves as a primary metric for university accreditation and the Conceito Preliminar de Curso (CPC).
What happens if a registered graduating senior misses the official ENADE exam?
Students designated as mandatory concluintes who miss the examination become irregular with INEP/MEC and are legally prohibited from graduating or receiving their diplomas. To regularize their status, they must file a formal dispensation request (pedido de dispensa) with documentary evidence (medical emergency, official duty, or force majeure) via the INEP portal during the designated window.
How does this 100-question practice bank align with the real ENADE Agronomia exam?
This practice bank adapts the official INEP Agronomia assessment matrix into 100 comprehensive multiple-choice items in English, incorporating realistic Brazilian agronomic scenarios, fertility calculations (calagem/gessagem), sprayer and irrigation engineering problems, phytosanitary resistance management, and environmental law questions, complete with 2-4 sentence teaching explanations for correct answers and specific rationales for incorrect options.
