Agricultural Science and Historiography Review

Vocabulary flashcards covering common chemical and organic fertilizers, historical concepts, the methodology and functions of historiography, and heritage conservation in relation to tourism.

Chemical Fertilizer (Phân bón hoá học)

Fertilizers produced through industrial processes utilizing natural or synthetic raw materials, primarily including nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, compound fertilizers, and micronutrient fertilizers.

Common Types of Chemical Fertilizers

As shown in Figure 7.1, common industrial chemical fertilizers: a) nitrogen fertilizer (phân đạm), b) phosphate fertilizer (phân lân), c) potassium fertilizer (phân kali), d) NPK compound fertilizer (phân hỗn hợp NPK), and e) micronutrient fertilizer (phân vi lượng).

Characteristics of Chemical Fertilizers

Fertilizers containing few nutrient elements but at high concentrations (e.g., urea contains $46\%$ nitrogen; $(NH_4)_2SO_4$ contains from $20.8\%$ to $21\%$ nitrogen; fused phosphate contains from $15\%$ to $21\%$ $P_2O_5$; $KCl$ contains from $58\%$ to $62\%$ $K_2O$). Most dissolve easily in water (except phosphate) for rapid uptake, though prolonged overuse can acidify soil and cause harmful residues.

Organic Fertilizer (Phân bón hữu cơ)

Organic substances buried into the soil and used in agriculture to supply nutrients to crops and improve soil quality.

Common Types of Organic Fertilizers

Common organic fertilizers including farmyard manure (livestock and poultry dung), peat, green manure, and compost/waste fertilizer (organic domestic/urban waste and treated plant residues).

The science that studies the entire past of mankind, covering individuals, groups, communities, nations, regions, or all of humanity.

Functions of Historiography (Chức năng của Sử học)

The scientific function (recovering past events and discovering laws of motion and historical development) and the social function (educating ideology, sentiment, morality, and extracting practical lessons).

Tasks of Historiography (Nhiệm vụ của Sử học)

Includes cognition (providing objective, truthful historical knowledge), education (transmitting traditional values, patriotism, tolerance, and human benevolence), and forecasting (predicting the future based on past lessons).

Historical Sources (Sử liệu)

All diverse forms of historical documentation and materials that contain information about humanity's past.

Steps in Historical Exploration

The sequential procedure for investigating history: 1) identifying the problem to explore, 2) preparing historical sources, and 3) solving the problem by exploiting the gathered sources.

Preparation of Historical Sources (Chuẩn bị sử liệu)

A foundational stage consisting of two basic tasks: collecting sources (listing and gathering relevant data) and processing source information (classifying, evaluating, authenticating, and comparing the collected sources).

Core Requirements of Heritage Conservation

Scientific standards in heritage work that mandate preserving the original state, retaining the original constituent elements of relics, and ensuring authenticity, integrity, and outstanding value.

Conservation of Tangible Cultural Heritage

Efforts to protect physical structures (such as citadels, tombs, communal houses, temples, pagodas, towers, and ancient houses) from structural deterioration and the negative impacts of nature and human activity.

Conservation of Intangible Cultural Heritage

Measures such as collection, archiving, craft transmission, and public performance to safeguard living traditions from the risk of extinction and transmit them across generations.

Conservation of Natural Heritage

Preservation activities that support biodiversity development, enhance the scientific value of natural sites, and contribute to local socio-economic growth.

Cultural Tourism Resources (Tài nguyên du lịch văn hóa)

Valuable assets for tourism comprising historical-cultural relics, revolutionary and archaeological sites, architectural monuments, traditional festivals, folk arts, and creative human achievements.

Chemical Fertilizer (Phân bón hoá học)

Fertilizers manufactured through industrial processes using natural or synthetic raw materials; primary categories include nitrogen, phosphorus, potassium, mixed fertilizers (containing two or more nutrient elements), and micronutrient fertilizers.

Common Types of Chemical Fertilizers (Hình 7.1)

The five main types of chemical fertilizers illustrated: (a) nitrogen fertilizer (phân đạm), (b) phosphorus fertilizer (phân lân), (c) potassium fertilizer (phân kali), (d) NPK mixed fertilizer (phân hỗn hợp NPK), and (e) micronutrient fertilizer (phân vi lượng).

Urea

A chemical nitrogen fertilizer characterized by a high nutrient content of $46\%$ nitrogen.

Ammonium Sulfate ($(NH_4)_2SO_4$)

A chemical nitrogen fertilizer containing from $20,8\%$ to $21\%$ nitrogen.

Fused Phosphorus Fertilizer (Phân lân nung chảy)

A phosphorus fertilizer containing from $15\%$ to $21\%$ $P_2O_5$; unlike most chemical fertilizers, it is not readily soluble in water.

Potassium Chloride ($KCl$)

A chemical potassium fertilizer containing from $58\%$ to $62\%$ $K_2O$.

Organic Fertilizer (Phân bón hữu cơ)

Organic materials incorporated into the soil in agriculture to supply nutrients to plants and improve the soil, including barnyard manure, peat, green manure, and composted domestic or urban organic waste.

Historical Reality (Hiện thực lịch sử)

All events and occurrences that took place in the past, existing objectively and independently of human subjective will.

History Perceived by Humans (Nhận thức lịch sử)

Human knowledge and understanding of historical reality, which is interpreted and reconstructed in various ways depending on research capacity, methods, available sources, and worldview.

Historiography (Sử học)

The scientific discipline that studies the entire past of mankind, whether focused on individuals, groups, communities, nations, regions, or all of humanity.

Scientific Function of Historiography (Chức năng khoa học)

The function of reconstructing past events and determining the fundamental nature of historical processes to discover the laws governing the progression and development of history.

The function of educating thoughts, sentiments, and ethics while drawing experiential lessons for contemporary life.
