Landbrugsvidenskab

Jorden er grundlaget for vores fødevareproduktion og fødevaresikkerhed. Den er hjem for mere end en fjerdedel af klodens biodiversitet og fungerer som planetens største vandfilter. FN har anslået, at hvis udpiningen af jorden fortsætter, vil mere end 90 % af klodens jorder være svært udpinte i 2050. Regenerativt landbrug er blevet beskrevet som en jordbrugsrevolution, der har potentialet til at vende denne udvikling ved at genopbygge jordfrugtbarheden og øge kulstofbindingen i jorden. Her præsenteres for første gang en række centrale skikkelser i den regenerative jordbrugsbevægelse i Danmark i en samtalebog, der giver et indblik i jordbrugernes arbejde og formidler et grundlæggende skifte i vores forståelse af, hvad jord overhovedet er.Sofie Isager Ahl (f. 1988) er forfatter og har skrevet ph.d. i antropologi om regenerativt landbrug. Hun har tidligere udgivet de skønlitterære bøger Naboplanter (2018) og Demeters latter (2022). I 2023 udkom den etnografiske monografi Regeneration, der tegner et portræt af en ny bevægelse af regenerative jordbrugere i Skandinavien.Sille Skovgaard (f. 1989) er uddannet økologisk jordbruger og antropolog med speciale i regenerativt landbrug. Hun har lavet filmen Jeg tror, vi starter som lys (med Emma Harris, 2024) om regenerative jordbrugeres eksperimenter med jordfrugtbarhed og sidder i bestyrelsen for foreningen Andelsgaarde.

Levedygtigt Landbrug er et bud på, hvordan vi kan løse de ­økologiske, ­økonomiske og sociale kriser, som det ­danske ­landbrug står i. I bogen skildrer Den Grønne Ungdoms­bevægelse en fremtids­vision for et jord­forbundet og retfærdigt ­land­brug og præsenterer de ­konkrete politiske tiltag, der kan føre os dertil. Et utopisk opråb for alt det, vi har at vinde.

Åsmund Bjørnstad er professor emeritus i planteforædling i Norge. I Kornbogen – brødets og øllets historie bygger han på det seneste tiårs indsigter indenfor genomforskning, arkæologi, kulturhistorie og bæredygtighedsforskning.Vi tæmmede kornet, og det os! Åsmund Bjørnstad formidler med kulturhistorisk spændvidde kornenes – det vil sige majsens, risens, hvedens, sorghums, hirsens, havrens og rugens – historie, fra vi begyndte at tæmme de vilde frø - og de tæmmede os. For ti, tolv, fjorten tusind år siden. Gennem denne kultivering opstod skriftsprog, tidsregning, religioner og klassesamfund – og den mangfoldighed af mutationer, som vi dagligt, uafvidende sætter på tallerkenerne. Eller svinger kruset med øl!Korn nok? Det var spørgsmålet for stenalderkvinden, som tæmmede kornet og frem til spørgsmålet ligesom gik i glemmebogen, og så lød det: Kød nok? Men nu er kornet igen kommet på den internationale dagsorden: Korn nok? At hver andet korn i dag går til dyrefoder eller til bioenergi, beskriver den nuværende udvikling. Kan den mon fortsætte – i et ændret klima, i en ny verdensorden?Bogens billedside er i absolut særklasse. Omkring 300 illustrationer rummer bogen.

Jord. Den mørke, fugtige masse, vi lever ovenpå, men som vi sjældent ser, fordi den er dækket af fliser, asfalt eller planter. Når vi graver, sår og planter til, er vi sjældent i tvivl; der udfolder sig et væld af liv i form af planter, rødder, frø og alskens kryb og kravl i jorden. Men hvad er det egentlig, og hvilken betydning har jorden for dyrkningen, klimaet og bæredygtigheden?Bogen tager dig med rundt i alt, du skal vide om jord, når du gerne vil dyrke jorden på bedste vis. Bogen er skrevet til dig, som gerne vil gå grundigt til værks, uden at du nødvendigvis har en masse haveerfaring. Bogen er krydret med illustrative fotos, tips og metoder.Om forfatterAnette Hougaard Nielsen er geolog og ph.d. i geografi og har skrevet en række artikler om klima, natur og miljø, både almene og videnskabelige.

Phosphorus (P) stands second to nitrogen in terms of its essentiality as a plant macronutrient, as well as due to its involvement in almost all plant developmental stages, primary and secondary plant metabolisms, maintenance of membrane structures, and in the structural skeleton of major biomolecules. An optimum P-supply also helps plants combat abiotic stress impacts. Most P in soil remains unavailable for uptake by plants. P-containing fertilizers are being added to agricultural lands to sustain high yields. Only the least amount of the applied P (20%¿30%) is used by most cultivated plants, and the rest remains as legacy P (P surpluses), which eventually causes eutrophication. This book, Phosphorus in Soils and Plants, reviews P in soils and plants, P dynamics in the soil¿water¿sediment environment, the major roles of P in the photosynthetic dark phase-biochemical pathways, major approaches for the sustainable management of P in agriculture, main mechanisms underlying the role of P in the regulation of plant¿microbe interactions in the rhizosphere, literature on the role of microbial phosphate solubilization in management of soil and plant nutrients, and insights into P recovery through waste transformation. This volume is an important resource for plant biologists involved in teaching or research who wish to advance their knowledge of P in soils and plants.

This book focuses solely on the issues of agricultural productivity analysis with advanced modeling approaches bringing solutions to food-insecure regions of the world, especially in south and southeast Asia and in Africa. Advanced modeling tools and their use in regional planning provide an outstanding opportunity to help face the challenges of climate change. The sudden effect of flash floods, drought, salinity, and sea water rises causing saltwater intrusions and its impact on agricultural production are some of the disastrous results of climate change.In this edited volume, information on climate-induced impacts for flooding, flash floods, and drought impact on agricultural crops is provided to address possible solutions for food security in south Asia, southeast Asia, and some regions of Africa. Leading-edge research methodology is presented as it relates to remote sensing applications for regional science and allied fields. In regional policy planning, agriculture andforestry play key roles in food security along with environmental conservation and depend on geo-spatial variability. Satellite remote sensing and geographical information systems have an immense potential to encompass all these factors and to catalogue the regional variability of climate change and climate economics. In the satellite remote sensing domain, advanced modeling tools, deep learning applications, and cloud-based earth engines significantly increase the flexibility of decision making and its application for regional perspectives. The result can increase agricultural and forest productivity and ensure its resilience and sustainability.The book¿s chapters introduce modeling techniques such as machine learning and fuzzy expert system using satellite remote sensing datasets based on cloud application. These methods assist regional planners to increase crop production, land use, and detection of changes in land cover in order to better understand their vulnerability toclimate-related disaster. Furthermore, remote sensing and in-depth GIS analysis are integrated with machine learning to address natural uncertainties such as flash floods, droughts, and cyclones so that emergency responses for agricultural production management can be adopted more effectively.

Sandy soils cover approximately 900 million ha worldwide, and there are extensive areas of sandy soils under cultivation. Most sandy soils have high water permeability, low water-holding capacity, low ability to retain and exchange nutrients, weakly developed soil structure and they may be prone to erosion by wind. As irrigation is required for obtaining good crop yields, there is a risk of substantial leaching of nutrients and pesticides, and ground water depletion. Due to global pressure on land resources, marginal soils such as sandy soils are taken into production or cultivated more intensely. Sandy soils ¿ as a group of soils with specific characteristics and ecological limitations ¿ have received limited research attention. This books presents the main papers from the Global Conference on Sandy Soils which was held in June 2023 in Madison, USA. This book focuses on novel and exciting aspects of research on sandy soils which is presented into three sections: Distributionand Assessment, Soil Carbon and Soil Health, and Water and the Environment. It presents a global glimpse on what recent progress has been in the study of sandy soil and their properties and management.

The world population is increasing while arable land is decreasing at an alarming rate. About one-quarter of arable land is degraded and needs significant restoration before it can sustain crops again. By 2030, the water supply will fall 40% short of meeting global demand. Moreover, looming climate change poses additional challenge to increasing food production to feed 10 billion people by 2050. Current major agricultural systems are on a largely unsustainable trajectory because of their contributions to greenhouse gas emissions, water pollution, and biodiversity loss.For these reasons, innovative technologies are being introduced in modern agriculture to sustain food production. They include digital and geospatial technologies to manage soil, climate and plant genetic resources. With the development of tools and sensors integrated into the internet of things (IoT) environment, physically collected information is converted into computer-readable language. Digital innovations thus allow real-time analysis, machine learning, and artificial intelligence (AI) that manage massive amount of data, also known as big data. Accordingly, digital agriculture affords greater potential for sustainable farming and economic benefits.This book summarizes the latest advances in AI-integration of agriculture practices. Specific focus includes but not limited to, big data, yield mapping, pests management, and optimal fertigation. As such, it presents a forward-looking approach to meet multiple UN Sustainable Development Goals, specifically, SDG 2, 6, 13 and 15.
